The equation P = 2(l + w) can be used to find the perimeter P of a rectangle with length l and width w. Solve the equation for w to produce a formula for finding the width of a rectangle given its perimeter and length.

The formula is w = (blank)

Answer:


w = (P)/(2) - l

Explanation:

P = 2(l + w)

Divide 2 to both sides:

P / 2 = l + w

Minus l to both sides:

P / 2 - l = w

Rewrite the equation:

w = P/2 = l
