Question

rectangle perimeter formula: ( p = 2l + 2w ) solve for w. perimeter is 136 feet and 42 feet?

Explanation:

Step1: Isolate the term with \( w \)

Given \( P = 2l+2w \), subtract \( 2l \) from both sides:
\( P - 2l=2w \)

Step2: Solve for \( w \)

Divide both sides by \( 2 \):
\( w=\frac{P - 2l}{2} \)

Answer:

\( w=\frac{P - 2l}{2} \)
