Given: A parallelogram with the dimension below
[tex]\begin{gathered} b=\text{base}=13yd \\ h=\text{height}=9yd \\ a=\text{slant side=10yd} \end{gathered}[/tex]To Determine: The area of the given parallelogram
The area of a paralleogram is given by the formula
[tex]A_{\text{PARALLELOGRAM}}=\text{base}\times height[/tex]Substitute the base and the height into the formula
[tex]\begin{gathered} A_{\text{PARALLELOGRAM}}=13yd\times9yd \\ A_{\text{PARALLELOGRAM}}=117yd^2 \end{gathered}[/tex]Hence, the area of the given parallelogram is 117yd²
