Question

Michael must build a rectangular storage shed. He wants the length to be 2.5 ft less than twice the width.

Answer 1

Answer:

Width = 7.6 ft.

Length = 12.7 ft.

Step-by-step explanation:

Perimeter of a rectangle (P) = 2L + 2W

where

P = 40.6 ft.

L = 2W-2.5

plugin values into the formula:

40.6 = 2(2W-2.5) + 2W

40.6 = 4W - 5 + 2W

40.6 + 5 = 6W

W = 45.6 / 6

W = 7.6 ft.

L = 2W-2.5

L = 2(7.6) - 2.5

L = 12.7 ft.

proof:

P = 2(12.7) + 2(7.6)

P = 40.6 ft.
