find the area of the triangle with base 2 1/5 yards and height 5/8 yard.( The area of a triangle equals half the product of its base and height)

A = (2 1/5 * 5/8)/2

A = (11/5) * 5/8) / 2

A = (55/40)/2

A = (55/40)* (1/2)

A = 55/80 = 11/16 sq. yards

11/16 sq yds

To find the area of a triangle, you can use the formula: area = (1/2) * base * height. In this case, the base is given as 2 1/5 yards, which can be written as a mixed fraction: 2 + 1/5 = 11/5 yards. The height is given as 5/8 yard.

Now, substitute the values into the formula:
area = (1/2) * (11/5 yards) * (5/8 yard)

We can simplify this calculation:
area = (1/2) * (11/5) * (5/8) * yards * yard
= (1/2) * (11/1) * (1/1) * yards * yard
= (11/2) * yards^2

Hence, the area of the triangle is 11/2 * yards^2.
