Question

The width of the rectangle is 0.7 meters less than the length. The perimeter of a rectangle is 52.6 meters. Find the dimensions of the rectangle. Show work.

Answer 1

• width: 12.8 m
• length: 13.5 m

Explanation:

Let L represent the length of the rectangle. The L-0.7 is the width, and the perimeter is ...

perimeter = 2×(length +width)

52.6 = 2(L +(L -0.7))

54 = 4L . . . . . simpify, add 1.4

13.5 = L . . . . . divide by 4

L -0.7 = 13.5 -0.7 = 12.8 . . . . width

The rectangle is 12.8 (width) by 13.5 meters (length).
