The area of a square is 25 in2. What’s the perimeter of the square?
The area of a square = Length of a side × Length of a side,
Length of a side=The area of a square ÷ Length of a side,
Perimeter of a square=4 ×Length of a side
Area = 25 in2 = 5 × 5
So the side length of the square =25 ÷ 5 = 5 in.
The perimeter of the square =4 × 5 = 20 in.
