The area of a square is given by:
S = a2
This means that in order to calculate the area of a square, multiply the lengths of two its sides on top of each other. As a result, if you know the area of a square, when you root from this value is possible to know the length of a side of the square.
Example: area of a square is 36 cm2, to find the side of this square, you must take the square root of the area values. Thus, the side length of the square 6 cm

To find the perimeter ofa square must add up the lengths of all its sides. Using the formula this can be expressed as:
P = a+a+a+a.
If you extract the square root of the area values of the squareand then fold the resulting value 4 times, we can find the perimeter of a square.
P = a+a+a+a.
If you extract the square root of the area values of the squareand then fold the resulting value 4 times, we can find the perimeter of a square.

Example: Given a square with area49 cm2 Yu. It is required to find its perimeter.
Solution:
You must first extract the square root of the square: √49 = 7 cm
Then, by computing the length of a side of a square, we can calculate the perimeter: 7+7+7+7 = 28 cm
Answer: the perimeter of a square areau 49 cm2 is 28 cm

Note
For square fair the following definitions:
A square is a rectangle that has equal sides.
A square is a special kind of rhombus, each of whose angles is equal to 90 degrees.
Being right in a square, around the square can be described or inscribed circle. The radius of the inscribed square in the circle can be found by the formula:
R = t/2, where t is the square side.
If the circle described around it, then its radius is:
R = (√2*t)/2
Based on these formulas, we can derive new to find the perimeter of a square:
P = 8*R, where R is the radius of the inscribed circle;
P = 4*√2*R, where R is the radius of the circumscribed circle.
The square is a unique geometric figure, since it is completely symmetrical, regardless of how and where to draw the axis of symmetry.
