We will discuss here how to find the perimeter of a square. Perimeter of a square is the total length (distance) of the boundary of a square.
In a square all the sides are of equal lengths.

Hence, perimeter of a square = 4l
We know that all the sides of a square are equal.
Perimeter of a Square
Perimeter of the square ABCD
= AB + BC + CD + AD
= 2 cm + 2 cm + 2 cm + 2 cm
= (2 × 4) cm
= 8 cm
Perimeter of a square is 4 times of s side.
Perimeter of a square = 4 × length of a side.
