ANSWER:
13.75 square feet
STEP-BY-STEP EXPLANATION:
Given:
Base = 15.5 feet
Height = 12 feet
Since it has the shape of a triangle, the area of the triangle is given by the following formula:
[tex]A=\frac{b\cdot h}{2}[/tex]We replacing:
[tex]\begin{gathered} A=\frac{15.5+12}{2} \\ A=\frac{27.5}{2} \\ A=13.75in^2 \end{gathered}[/tex]the area of the foundation is 13.75 square feet
