Question

The length of a rectangle is 5 centimeters greater than its width. The perimeter is 58 centimeters. What are the dimensions of the rectangle

Answer 1

Let w = the width

Let w + 5 = the length

P = 2l + 2w

58 = 2(w+5) + 2w

58 = 2w + 10 + 2w

48 = 4w

12 cm = w

w + 5 = 12 + 5 = 17 cm, length
