Given:
square shape
Perimeter 28 feet
Find its area

A square has 4 equal sides, so perimeter is 4a

Perimeter = 4a
28 ft = 4 a
28 ft / 4 = a
7 = a

One side of the the square is 7 ft.

Area of a square is the measure of one side raised to the power of 2.

A = a²
A = (7 ft)²
A = 49 ft²

A square has sides of equal length.
So 28 ÷ 4 = 7.
Then to work out the area, you have to multiply the length by the width.
So 7 × 7 = 49ft².
Hope this helped :)
