Answer 2

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{area of a triangle}\\ \cline{1-1} \\ A=\cfrac{1}{2}bh~~ \begin{cases} b=base\\ h=height \end{cases} \\\\ \cline{1-1} \end{array}~\hspace{7em} \begin{array}{|c|ll} \cline{1-1} \textit{area of a square}\\ \cline{1-1} \\ A=s^2\qquad \begin{array}{llll} s=length~of\\ \qquad a~side \end{array} \\\\ \cline{1-1} \end{array}$
