Question

1. solve for w: p = 2l + 2w (perimeter of a rectangle)

Explanation:

Step1: Isolate the term with W

Subtract 2L from both sides.
$P - 2L=2L + 2W- 2L$
$P - 2L = 2W$

Step2: Solve for W

Divide both sides by 2.
$\frac{P - 2L}{2}=\frac{2W}{2}$
$W=\frac{P - 2L}{2}$

Answer:

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