If the perimeter of a rectangle is ft and its length is ft what is its width?

To find the width of a rectangle given its perimeter (P) and length (L), you can use the formula for perimeter: ( P = 2(L + W) ), where W is the width. Rearranging the formula gives ( W = \frac{P}{2} - L ). Plug in the known values for P and L to calculate the width.
