ANSWER
[tex]l=\frac{A}{w}[/tex]EXPLANATION
We want to solve for the length, l, in the formula for the area of a rectangle:
[tex]A=lw[/tex]We simply want to make the length the subject of the formula. To do this, divide both sides of the formula by w:
[tex]\begin{gathered} \frac{A}{w}=\frac{lw}{w} \\ \Rightarrow l=\frac{A}{w} \end{gathered}[/tex]That is the answer.
