Question

makayla is taking a math course and is working with the perimeter of rectangles. she knows the perimeter and length of her rectangle and wants to solve for the width. rearrange the following equation for (w), where (p) is the perimeter, (l) is the length, and (w) is the width of the rectangle.
(p = 2l+2w)

o a (w = 2p - 2l)
o b (w=\frac{p}{2}-2l)
o c (w=\frac{p - 2l}{2})
o d (w = 2p+2l)

Explanation:

Step1: Start with the perimeter formula

$P = 2L+2W$

Step2: Isolate the term with $W$

$2W=P - 2L$

Step3: Solve for $W$

$W=\frac{P - 2L}{2}$

Answer:

C. $W=\frac{P - 2L}{2}$
