Question

A square photograph has a perimeter of 20 inches. What is the area of the photograph?

Answer 1

Since it's a square, it must have 4 equal sides.
20 / 4 = 5
The formula for area: Area = length x width
4 x 5 = 20.
The area is 20 inches! (Don't forget, the answer is squared!)

Answer 2

Area of square is 25 inches²

Explanation:

Given : A square photograph has a perimeter of 20 inches.

We have to find the area of the photograph.

We know perimeter of square is 4a , where a is side of square

Given : perimeter of square = 20 inches

4a = 20

Divide both side by 4, we get,

a = 5 inches

Also, Area of square = side × side

Area of square = 5 × 5

Area of square = 25 inches²

Thus, area of square is 25 inches²
