Question

1. The length of a rectangle is 8 inches more than its width. The perimeter of the rectangle is 24 inches. What are the width and length of the rectangle?

2. The length of a rectangular garden is 3 yard more than twice its width. The perimeter of the garden is 36 yard. What are the length and width of the garden?

Answer 1

1. L = W +8

24 = 2L + 2W = 2(W+8) + 2W = 2W + 16 + 2W = 16 + 4W

Solve for W then L.

2. Use same method as 1.
