The perimeter of a rectangle is given by the formula p=2L+2W, where L is the length and W is the width. Solve for L in terms of P and W.

Question

The perimeter of a rectangle is given by the formula p=2L+2W, where L is the length and W is the width. Solve for L in terms of P and W.

Answer 1

"Solve for L" means manipulate the equation to get the L by itself on one side of the equation, and everything else on the other side:

 

P = 2L + 2W

P - 2W = 2L

(P-2W)/2 = L
