Question

The length of a rectangular mailing label is

22
centimeters less than twice the width. The perimeter is
6262
centimeters. Find the dimensions of the label.

Answer 1

Let w be the width

Then the length is 2w - 2

We also know that the perimeter is 62 cm. The perimeter is the distance around the rectangle, or 2w + 2(2w - 2).

So, 2w + 2(2w - 2) = 62

2w + 4w - 4 = 62

6w = 66

w = 11

So, the length is 2w - 2 = 2(11) - 2 = 22 - 2 = 20

Length = 20 cm

Width = 11 cm
