The perimeter of a certain square is 8 feet. whatis its area?

Perimeter: P = 4(a) = 4 × 2 = 8

To find the area:

Perimeter ÷ 4 (since a square has 4 sides) = 2
Length of one side of a square = 2

Formula of area: length × width = area

Area : 2 × 2 = 4

The area of the square is 4

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
