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.
