Question

If the perimeter of a square is 14d+28 centimeters, what is the length, in centimeters, of each side of the square?

Answer 1

Each side is (7/2d +4) cm

Explanation:

The perimeter of a square is given by

P = 4s where s is the side length

14d +28 = 4s

Divide each side by 4

14d/4 +28/4 = 4s/4

7/2d +7 = s

Each side is (7/2d +4) cm
