A rectangle has perimeter P, length l and width w. Which of the follwoing represents l in terms of P and w?

Answer: L=P/2-W

Explanation:

The definition of a perimeter is the total distance around a polylon. That means you add all of the side together to find the total distance of a polygon.

First we use the formula of the perimeter of the rectangle. In a rectanble, there are two sides that are L lenght and there are two sides that are W, width.

Then we from the perimeter which is W+W+L+L. Then you combine like terms. W+W+L+L=2W+2L=P

Now you are ready to solve to L.

2L+2W=P

2 (L+W) = p

L+W=P/2

L=P/2-W
