Question

Solve the formula for the perimeter of a rectangle with width w and length l,for the length P=2w+2l solve for l

Answer 1

Answer:

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

Step-by-step explanation:

we know that

The formula for the perimeter of a rectangle is equal to

$P=2(w+l)$

where

l is the length

w is the width

Solve for l

That means ----> Isolate the variable l

Divide by 2 both sides

$\frac{P}{2}=\frac{2(w+l)}{2}$

Simplify right side

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

Subtract w both sides

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

Simplify right side

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

Rewrite

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

Answer 2

Answer:Solve P = 2l + 2w for w.

The first step is to isolate the variable term, 2w.
