Answer:


A=470(1)/(4)ft^2

Detailed Explanation: The area of the figure provided is the sum of two areas, a rectangle, and a triangle:

The total area is calculated next, and the necessary steps are shown as follows


\begin{gathered} A=A_1+A_2 \\ A_1=(1)/(2)(b\cdot h)=(1)/(2)\cdot\lbrack(25ft-22.5ft)*19.8ft\rbrack \\ A_1=(1)/(2)\cdot\lbrack2.5ft*19.8ft\rbrack=(49.5ft^2)/(2)=24.75ft^2 \\ A_1=24.75ft^2 \\ A_2=w\cdot h=22.5ft\cdot19.8ft=445.5ft^2 \\ A_2=445.5ft^2 \\ \therefore\Rightarrow \\ A=A_1+A_2=24.75ft^2+445.5ft^2 \\ A=470.25ft^2 \\ A=470(1)/(4)ft^2 \end{gathered}
