If the perimeter of a rectangle is 24 and the length is 2 times the width what is the length and width

Answer 1

Rectangle Perimeter = 2 (L + W)

L = 2W Substitute it into the equation above

If 24 = 2 (2W + W)

24 = 4W + 2W

24 = 6W

W = 4

Plug the width back into the equation to solve for the length

24 = 2 (L + 4)

24 = 2L + 8

16 = 2L

L = 8

Therefore, the length is 8 and the width is 4.
