Use the formula for the area of a triangle to determine the area of a triangle with base equal to 13 yd and height equals to 5 yards.
The formula for the area of a triangle is:
Area = 1/2 * base * height
Given that the base is 13 yards and the height is 5 yards, we can plug these values into the formula to find the area:
Area = 1/2 * 13 * 5
Area = 1/2 * 65
Area = 32.5 square yards
Therefore, the area of the triangle is 32.5 square yards.
