To answer this question we will use the following formula for the area of a trapezoid:
[tex]Area=\frac{(MajorBase+MinorBase)*height}{2}.[/tex]
Substituting MajorBase=5yd, MinorBase=3yd, and height=3yd we get:
[tex]Area=\frac{(5yd+3yd)*3yd}{2}.[/tex]
Simplifying the above result we get:
[tex]\begin{gathered} Area=\frac{8yd*3yd}{2}=\frac{24yfd^2}{2} \\ =12yd^2. \end{gathered}[/tex]
Answer: Option D.
