Question

The length of a rectangle is 4 meters longer than the width. If the area is 40 square meters, find the rectangles dimentions. Round to the nearest tenth of a meter

Answer 1

L = 32

W = 8

Explanation:

Set it up algebraically:

A = L x W

A = 40 m^2

L = 4w

40 = 4w x w

40 = 5w

40/5 = 5w/5

W = 8

L = 4(8)

L = 32
