Question

solve the formula $a = lw$ for $l$. \
\
\bigcirc a. $l = \frac{w}{a}$ \
\bigcirc b. $l = wa$ \
\bigcirc c. $l = a - w$ \
\bigcirc d. $l = \frac{a}{w}$

Explanation:

Step1: Isolate $l$ via division

To solve $A = lw$ for $l$, divide both sides by $w$.
$\frac{A}{w} = \frac{lw}{w}$

Step2: Simplify the right-hand side

The $w$ terms cancel out on the right.
$l = \frac{A}{w}$

Answer:

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