Question

A rectangular parking lot has a perimeter of 88 meters. The length of the parking lot is three times the width. Find the length and the width.

Answer 1

W=11, L=33

Step-by-step explanation: The following formula for the perimeter relates all of the given information:

P=2L+2W

So we substitute in the given information and solve for W to find

88=2(3W)+2W

88=6W+2W

88=8W

Then divide each side by 8.

11=W

The width is 11 meters. The length is then

L=3W

=3(11)

=33

or 33 meters.
