Question

The length of a rectangle is 5 cm less than twice the width. The perimeter of the rectangle is 80 cm. Find the dimensions

Answer 1

Answer:

W=16 2/3

L=28 1/3

Step-by-step explanation:

L=2W-5

80=2W+2L

80=2W+2(2W-5)

80=2W+4W-20

80=6W-20

100=6W

W=16 2/3

L=2(16 2/3)-5

L=33 1/3 -5

L=28 1/3
