Question

1. area of a rectangle. solve for w: a = lw. solve for the indicated variable.

Explanation:

Step1: Isolate the variable w

Given the formula for the area of a rectangle $A = lw$. To solve for $w$, we divide both sides of the equation by $l$.
$A\div l=lw\div l$

Step2: Simplify the equation

On the right - hand side, $\frac{lw}{l}=w$, and on the left - hand side we have $\frac{A}{l}$. So $w=\frac{A}{l}$.

Answer:

$w = \frac{A}{l}$
