A square is a closed geometric shape which consists of 4 sides and hence 4 respective angles. The most important characteristic of a square is that all its 4 sides are equal to each other in length. And therefore, all its angles are also equal to each other. Each angle in a square is equal to 90° and the sum of all the 4 angles in a square adds up to 360°. The area and the perimeter of a square can be easily calculated by using their appropriate formulas.

Example 1: What is the area of a square whose side length is 10m?

Given: side length of a square, s = 10m

In order to calculate the area of a square, we can use its area formula.

Area of a square, A = (side)2 = s2

Applying the above formula, we get: Area of a square, A = (10m)2

This gives: Area, A = 100m2

Therefore, area of the given square is 100m2.

Example 2: What is the perimeter of a square whose length of the side is 12m?

Given: side length of a square, s = 12m

In order to calculate the perimeterof a square, we can use its perimeter formula.

Perimeter of a square, P = (4 * side) = 4s

Applying the above formula, we get: Perimeter of a square, P = 4 * 12

This gives: Perimeter, P = 48m

Therefore, perimeter of the given square is 48m.
