ANSWER


81ft^2

Step-by-step explanation

The area of a trapezoid is generally given as:


A=(1)/(2)(a+b)h

where a = length of short base

b = length of long base

h = height

Therefore, we have that the area of the trapezoid is:


\begin{gathered} A=(1)/(2)(3+15)\cdot9=(1)/(2)\cdot18\cdot9 \\ A=81ft^2 \end{gathered}
