If the perimeter and area of a square are numerically equal then the side of the square is:

Correct option is A

Given:

Perimeter and area of a square are numerically equal.

Formula Used:

Perimeter of a square = 4 × side

Area of a square = side²

Solution:

Let the side of the square be 's'.

Perimeter of the square = 4s

Area of the square = s²

Since the perimeter and area are numerically equal, we have:

4s = s²

Divide both sides by s (assuming s ≠ 0):

4 = s

Therefore, the side of the square is 4 units.
