Use the formula for the area of a triangle to determine the area of a triangle with a base equal to 13 yards in height equal to 5 yards

The formula for the area of a triangle is:

Area = (1/2) x base x height

Substitute the given values into the formula:

Area = (1/2) x 13 yards x 5 yards
Area = (1/2) x 65 square yards
Area = 32.5 square yards

Therefore, the area of the triangle is 32.5 square yards.
