15 ft
10 ft
20 ft
Find the area of the trapezoid

Answer 1

`\textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} h~~=height\\ a,b=\stackrel{parallel~sides}{bases~\hfill }\\[-0.5em] \hrulefill\\ a=15\\ b=20\\ h=10 \end{cases}\implies A=\cfrac{10(15+20)}{2}\implies A=175~ft^2`

Answer 2

The formula for area of trapezoid is A= a+b/2 • h. If you plug in the numbers, you get 175.
