What is Perimeter
Perimeter of Square is to sum of length of all its four sides
Perimeter of Square = side + side + side + side
We know that in square all sides are equal, so we get;
Perimeter of Square = 4 side
P = 4s
Example 1  In the following Square ABCD
Perimeter of Square = 4 s
P = 4 * 5
P = 20 cm
Example 2  In the following Square PQRS
Perimeter of Square = 4 s
P = 4 * 3
P = 12 cm
