Question

the perimeter of a rectangle is given by the formula $p = 2l + 2w$, where $p$ is the perimeter, $l$ is the length, and $w$ is the width. which formula can be used to solve for the width $w$? $w=\frac{p + 2l}{2}$ $w=\frac{2}{p + 2l}$ $w=\frac{p - 2l}{2}$ $w=\frac{2 + 2l}{p}$

Explanation:

Step1: Start with perimeter formula

$P = 2l+2w$

Step2: Isolate term with $w$

$P - 2l=2w$

Step3: Solve for $w$

$w=\frac{P - 2l}{2}$

Answer:

C. $w=\frac{P - 2l}{2}$
