# Advice 1: How to find the perimeter of the hexagon

As you know, the perimeter of a plane figure is the length of the bounding lines. To find the perimeter of a polygon is sufficient to add the lengths of its sides. It will have to measure the length of all component segments. If polygon is correct, then the task of finding the perimeter much easier. You will need
• - the range;
• a pair of compasses.

To find the perimeter of the hexagon, measure and add the lengths of all six sides. P = A1+A2+A3+A4+A5+A6,where P is the perimeter of the hexagon, and A1, A2 ... A6 – the length of its sides.The units of each of the parties reduced to a single species, in this case, it is sufficient to store only the numerical values of the lengths of the sides. The unit of measure of the perimeter of the hexagon will coincide with the unit of measure of the parties.

Example.A hexagon with side lengths 1 cm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm. is Required to find its perimeter.Solution.1. The unit of measurement of the first side (cm) differs from the units of measurement of the lengths of the other sides (mm). Therefore, move: 1 cm = 10 mm. 2. 10+2+3+4+5+6=30 (mm).

If the hexagon is correct, then to find its perimeter, multiply the length of its side six:R = a * 6,where a is the length of sides of a regular hexagon.Example.To find the perimeter of a correct hexagon with side length equal to 10 cm Solution: 10 * 6 = 60 (cm).
4
A regular hexagon has a unique feature: the radius of the circumscribed around this hexagon of a circle is equal to the length of its side. So, if you know the radius of the circumscribed circle, to use the formula:P = R * 6,where R is the radius of the circumscribed circle.

Example.To calculate the perimeter of a right hexagon, wrote in a circle of diameter 20 cm Solution. The radius of the circumscribed circle will be equal to: 20/2=10 (cm).Therefore, the perimeter of the hexagon: 10 * 6 = 60 (cm).

If a task is set to the radius of the inscribed circle, apply the formula:P = 4 * √3 * r,where r is the radius inscribed in a regular hexagon circle.
7
If you know the area of the right hexagon, then to calculate the perimeter use the following ratio:S = 3/2 * √3 * A2,where S – area of a regular hexagon. Here you can find a = √(2/3 * S / √3), hence:P = 6 * a = 6 * √(2/3 * S / √3) = √(24 * S / √3) = √(8 * √3 * S) = 2√(2√3).

# Advice 2 : How to find the area of the hexagon

By definition of the right of plane geometry a polygon is a convex polygon whose sides are equal and angles are also equal. A regular hexagon is the right polygon with number of sides equal to six. There are several formulas for calculating the area of a regular polygon. Instruction

If you know the radius of the circle circumscribed about a polygon, then its area can be calculated by the formula:

S = (n/2)•R2•sin(2π/n), where n is the number of sides of the polygon, R is the radius of the circumscribed circle, π = 180º.

In a regular hexagon all the angles equal to 120°, so the formula would be:

S = √3 * 3/2 * R2 2
In the case where a circle with radius r is inscribed in a polygon, its area is calculated by the formula:

S = n * r2 * tg(π/n), where n is the number of sides of the polygon, r is the radius of the inscribed circle, π = 180º.

For hexagon, this formula takes the form:

S = 2 * √3 * r2 3
Area of a regular polygon can also be calculated knowing only the length of its sides using the formula:

S = n/4 * a2 * ctg(π/n), n is the number of sides of the polygon, a is the length of sides of the polygon, π = 180º.

Accordingly, the area of the hexagon is equal to:

S = √3 * 3/2 * a2 Search
