# Advice 2 : How to calculate the perimeter

Circumference: L = 2nr = πd

p is the number "PI". It is always equal to 3.14

Application method is done using a special device odometer. It is based on a toothed roller, in this case we know what is the distance between its teeth. Accordingly, this device has the counter passed the teeth, and let us then, by multiplying the distance between the teeth on the passed their number to the perimeter.

The scientific method is carried out using mathematical analysis, namely: integration of the equation of the curve that describes the boundary.

# Advice 4 : How to calculate the area of the walls

- Roulette
- Rake
- Spirit level
- A sheet of paper with a pencil or calculator
- Of stool or ladder

If the room has a niche, compute separately the area of the walls of the niche and the area of the other walls.

Decide whether to glue the Wallpaper to the ceiling or leave a free stripe on top. Determine what will be the width of this strip and subtract its square from the square walls.

The height measure together. Combines single zero roulette with the point of intersection of the vertical line and the ceiling, the other looking mark at the intersection with the floor or the baseboard.

If you do not have roulette, you can use a long cord. Tie a knot in it and align it with the point of intersection of angular lines and ceiling. Pull the cord and at the intersection of it with the floor tie the second knot. The distance between the knots can be measured with a regular ruler.

# Advice 5 : How to find the area of a room

**the area**

**of the room**. This may be required when repair to calculate the amount of paint or floor covering, when buying new furniture or remodeling apartments. In the accompanying documents to the apartment or house is usually stated a total useful

**area**of housing, therefore the size of each

**room**separately will have to calculate yourself.

**the area**of a rectangle, you multiply the length by the width. Accordingly, in order to find out

**the area**

**of a room**, multiply the length of its sides.

**of the room**. Do it better by using construction tape, which has a sufficient length and keeps a smooth shape. The length and width

**of the room**measure along the walls. This frees up space near the wall and put the tape measure along the floor. Important to make sure that the measuring tapes are not twisted and not stretched excessively. The obtained data it is better to write down on a piece of paper so you don't have to measure again.

**of the room**– length and width, and do the necessary calculations. For example, if the longest side is 5 m and 3 m,

**the area**of the entire

**room**will be 5x3 = 15 sq. m. it Should be note that if the lengths are always measured in meters, then

**the area of**the surface of the floor or ceiling only in square meters.

# Advice 6 : How to calculate the area of walls

**the area**of the treated surface.

- Measuring tape

**area**

**of walls**in one room is very simple.

The total

**area**needs to be folded from square of all the (usually) four

**walls**OK, they're all the same, but some have Windows, doors and similar structures. S=S1+S2+S3+S4.

**area**of one

**of the walls**, you should multiply the height

**of the walls of the**ing on its length. If it does not, it will be the first

**area**S1. Similarly, the calculated

**area**of the other three

**walls**S2, S3, S4. And

**the area of**those

**walls**, where there is, for example, window, calculated as: measured width and length of the window are multiplied by each other, it turns out

**the square**window, the size of a

**wall**, s is subtracted

**the area of**the window, this will be

**the area of**the

**walls**s, where encased window, door, etc.

# Advice 7 : How to measure the area of a room

**the area of**each

**room**. Such data are necessary for calculating needed materials and cost estimates of the repair costs. Typically, the measurement of

**the room**is straightforward and requires simple improvised tools.

- Construction tape measure, calculator, paper or notebook, pencil (pen)

**of the room**on the width so you get the desired

**area**of the room in meters.

**of the room**into individual rectangles. Measure the dimensions of the resulting space, determining the length and width of rectangles.

**of the room**on a sheet of paper, this does not have to be perfect to follow all the proportions. Apply a sketch the results of measurement. Then multiply the length and width of each of the individual rectangles and record their

**area**. The final stage of the measurement consists in adding the areas of the resulting shapes.

**area**, and then subtract from the total area

**of the room**the result.

**area**occupied by Windows and doors.

**area**of the room.

**room**in the apartment. Having such a pivot table, you can very accurately calculate the number of finishing materials for walls and flooring.

# Advice 8 : How to calculate the area of a room

- - the tape or the tape;
- pencil.

# Advice 9 : How to find the perimeter if you know area

**Area**and

**perimeter**- basic numerical characteristics of any geometric shapes. Finding these values is facilitated by the generally accepted formulas in which you can calculate through one another with little or no additional initial data.

# Advice 10 : How to calculate the perimeter of the room

**the perimeter**

**of the room**. Believe me, this did not need to have a deep knowledge in the field of geometry and algebra, it is enough to remember the school course of mathematics.

- roulette;
- pencil and paper;
- thread.

**perimeter**, measure the length of one side and multiply the result by four. The final number will be the perimeter of your

**room**.

**the perimeter**

**of the room**.

**of the perimeter**. The place where she merges with the beginning of the reference must be noted. And then measure the resulting length. The result of this measurement will be the perimeter of your

**room**.

# Advice 11 : How to calculate consumption Wallpaper

**The calculation ****should start with the perimeter**. The scheme of calculation is simple: add up the lengths of adjacent walls and multiply by 2. Example: if one wall is 3 meters and the other 4, then the perimeter is 14 meters.

You need to consider **amendments in niches and ledges**. If they are in the apartment, and the perimeter of the think differently. The perimeter is the sum of the lengths of each wall, measured along the floor.

**Windows and doors are better not to subtract**. Experts recommend that you do, despite the fact that the pasted over surface data elements are not included. Traditionally, the area of door and window openings left in reserve.

**Do I need to glue the Wallpaper behind the furniture?** If the furniture you have no plans to rearrange, then glue the Wallpaper over it's not necessary. If the wall is fully covered by a wardrobe or a rack, the perimeter to include it is not necessary.

For Wallpaper with a pattern, it is important **to take into account the rapport.** Rapport is called the pitch of the repeating pattern on the Wallpaper. The size of the repeat is indicated on the packaging. To the height of each leaf is added this value. Otherwise, the matching pattern between the two blades will not work.

To **determine the height of the canvas**, you need to know the height of the room. To height added rapport and if necessary, the step offset. Plus 8 - 10 cm for trimming the top and bottom of the canvas.

In order **to determine the desired number of blades**, you need to know the width of the roll. It is always indicated on the package. Usually the standard width, 53 cm Perimeter of the room and divide by the width of the roll, the result of rounding in a big way. Example: the perimeter of our room is 14 m, divide it by 53cm to round 27 and get the paintings.

**How many paintings per roll we will determine **if we divide the length of the roll to the height of the canvas. In this case, the figure is rounded down.

**How many rolls needed for a room**, we'll know if you need the room number of rolls divide by the number of blades in the rolls. To the result add the stock, 1 roll.

Leave the coil on the stock you need in the event of marriage. Because there is always the risk to damage 1 - 2 canvases when gluing. As the spare roll is required for emergency repairs in the future, in order to seal othersise or soiled area.
