To find the area of a triangle, you can use the formula:
\[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \]
In this case, the base is 13 yards and the height is 5 yards. Plugging these values into the formula, we have:
\[ \text{Area} = \frac{1}{2} \times 13 , \text{yards} \times 5 , \text{yards} \] \[ \text{Area} = \frac{1}{2} \times 65 , \text{square yards} \] \[ \text{Area} = 32.5 , \text{square yards} \]
Therefore, the area of the triangle is \(32.5\) square yards.
