Question

In a rectangle, if an area

Answer 1

`\textit{area of a rectangle}\\\\ A=Lw ~~ \begin{cases} L=length\\ w=width\\[-0.5em] \hrulefill\\ A=12√(30)\\ w=3√(5) \end{cases}\implies 12√(30)=L3√(5)\implies \cfrac{12√(30)}{3√(5)}=L \\\\\\ 4\cdot \cfrac{√(30)}{√(5)}=L\implies 4\cdot \sqrt{\cfrac{30}{5}}=L\implies 4√(6)=L`
