# The length of a rectangle is four time the width. if the area of the rectangle is 16 square inches, what is the length and the width

$\bf \textit{area of a rectangle}=l\cdot w\qquad \begin{cases} l=length\implies 4\cdot w\implies 4w\\ w=width\\ --------------\\ area=16 \end{cases} \\ \quad \\ 16=(4w)w\impliedby \textit{solve for "w"}$
