Answer:

Width = 230 ft.

Step-by-step explanation:

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

where;

P = 1120 ft.

L = 100 + W

find:  Width (W)

plugin values into the formula:

1120 = 2(100 + W) + 2W

1120 = 200 + 2W + 2W

1120 - 200 = 4W

W = 920 / 4

W = 230 ft.

proof:

P = 2(100 + 230) + 2(230)

1120 = 660 + 460

1120 = 1120 ---ok
