Question

1. given the formula for perimeter of a rectangle. solve for the width \w\. p = 2w + 2l, where l = length and w = width

p = 2w + 2l\tgiven problem

Explanation:

Step1: Isolate the term with width

Subtract $2l$ from both sides of the equation $P = 2w+2l$.
$P - 2l=2w + 2l-2l$
$P - 2l = 2w$

Step2: Solve for width

Divide both sides of the equation $P - 2l = 2w$ by 2.
$\frac{P - 2l}{2}=\frac{2w}{2}$
$w=\frac{P - 2l}{2}$

Answer:

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