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 in these values:
\[ \text{Area} = \frac{1}{2} \times 13 \times 5 \]
Calculating this step-by-step:
-
Multiply the base and height: \( 13 \times 5 = 65 \)
-
Divide by 2: \( \frac{65}{2} = 32.5 \)
So, the area of the triangle is 32.5 square yards.
The correct response is: 32.5 square yards.
