Answer 1

Answer

Let the side of a square be a.
The perimeter of a square is numerically equal to its area.
perimeter of a square=4a.
Area of square =a²
Given
4a=a²
or, a(a−4)=0
or, a=4 [ Since a is not equal to 0]
Area of square =a²=4×4=16 square units.

Step-by-step explanation:

P = A

x = x

4s = s*s

Therefore, 4 = (s*s) / s

4 = s

Therefore area = 16
