A formula for finding the perimeter of a rectangle is P=2L+2W

. If you know the perimeter (P)
and width (W)
of a rectangle, which formula can you use to find the length (L)
?

CLEAR CHECK

L=P−2W−2

L=P/4W

L=P/2 − W

L=P/2 − 2W

The correct formula to find the length (L) of a rectangle is L=P/2 − W.
