Question

2. The width of a rectangle is 3 feet shorter than its length. The perimeter is 530 feet. Let x equal the length of the rectangle. The formula is P = 2l + 2w. What are the length and the width of the rectangle?

Answer 1

length: 134 ft; width: 131 ft

Explanation:

If x is the length of the rectangle then x-3 is the width and the perimeter is ...

530 = 2x +2(x-3) = 4x -6

536/4 = x = 134 . . . . . . . . add 6 and divide by 4

The length of the rectangle is 134 ft; the width is 131 ft.
