Question

The perimeter of a rectangular window is 43 feet. The width of the window is 5 ft more than the length. Find the width of the window

Answer 1

13.25 ft

Explanation:

Let w represent the width of the window. Then w-5 represents the length, and the perimeter is ...

P = 2(L+W)

43 = 2((w-5) +w) = 4w -10

53/4 = w = 13.25 . . . feet

The width of the window is 13.25 ft.
