To find the area

*of a square*multiply the length value by the value of width. As the square length and width are the same, then the value enough to square. Thus, the area of a square equals length of its side squared. A unit of area can be square millimeters, centimeters, decimeters, meters, kilometers.To determine the area of a square, you can use formulas = aa, where S is the area of a square and the side of the square.2

Example No. 1. The room is square-shaped. How much plastic (in square metres) will be required in order to completely cover the floor, if the length of one side of the room is 5 meters.Write down the formula: S = aa. Substitute it specified in the condition data.Since a = 5 m, hence the area will be Ravna (room) = 5x5= 25 sq m, so and S (laminate) = 25 sq. m.

The perimeter is the total length of the border. Squared perimeter is the length of all four, with the same sides. That is, the perimeter of the square is the sum of all its four sides. To calculate the perimeter of a square, it is sufficient to know the length of one side. Perimeter is measured in millimeters, centimeters, decimeters, meters, kilometers.To define a perimeter formula:P = a + a + a + a Ilir = 4a, gder perimeter,and side length.

Example No. 2. For finishing works of the premises in the form of a square required ceiling moldings. Calculate the total length (perimeter) skirting, if the value of one side of the room is 6 meters. Write down the formula P = 4a.Substitute it specified in the condition data:P (room) = 4 x 6 = 24 meters.Consequently, the length of the ceiling moldings will also be equal to 24 meters.
