Answer 1

Answer:

$l=\frac{A-\frac{1}{2} \pi w^2}{2w}$

Step-by-step explanation:

We essentially need to solve for l; in other words, we must isolate it to one side.

First, notice that the term $\frac{1}{2} \pi w^2$ doesn't have any l terms in it, so we can just move this to the left side by subtracting both sides by $\frac{1}{2} \pi w^2$:

A - $\frac{1}{2} \pi w^2$ = 2lw

Now, the right side has 2lw, so we must divide both sides by 2w to isolate l:

$l=\frac{A-\frac{1}{2} \pi w^2}{2w}$
