Question

Find area of the whole shape

Answer 1

`\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} a,b=\stackrel{bases}{parallel~sides}\\ h=height\\ \cline{1-1} a = 5.3\\ b = 11.5\\ h= 5 \end{cases}\implies A=\cfrac{5(5.3+11.5)}{2} \\\\\\ A=\cfrac{5(16.8)}{2}\implies A=5(8.4)\implies A=42`
