Answers: 2
![\bf \textit{area of a rectangle}\\\\ A=Lw~~ \begin{cases} L=length\\ w=width\\[-0.5em] \hrulefill\\ A=360\\ \stackrel{\textit{10 times as wide}}{L=10w\qquad } \end{cases}\implies 360=(10w)(w)\implies 360=10w^2 \\\\\\ \cfrac{360}{10}=w^2\implies 36=w^2\implies \sqrt{36}=w\implies \boxed{6=w} \\\\\\ L=10w\implies \boxed{L=60}](/tpl/images/0075/3337/1b81c.png)
