![\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\ \cline{1-1} A=196\pi \end{cases}\implies 196\pi =\pi r^2\implies \cfrac{196\pi }{\pi }=r^2 \\\\\\ 196=r^2\implies \sqrt{196}=r\implies 14=r \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{\textit{perimeter of the rectangle}}{12r\implies 12(14)\implies 168}~\hfill](/tpl/images/0211/3426/784ab.png)
