The area of a triangle can be calculated using the following formula:
[tex]A=\frac{bh}{2}[/tex]
Where "b" is the base and "h" is the height.
In this case, you can identify that:
[tex]\begin{gathered} b=6.4yd \\ h=5yd \end{gathered}[/tex]
Then, you can substitute values into the formula and then evaluate, in order to find the area of the given triangle:
[tex]\begin{gathered} A=\frac{(6.4yd)(5yd)}{2} \\ \\ A=\frac{32yd^2}{2} \\ \\ A=16yd^2 \end{gathered}[/tex]
Hence, the answer is:
[tex]A=16yd^2[/tex]
