Answer:
12 3/4 square yards
Explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
Your figure shows a triangle with a base of b=8 1/2, and a height of h=3. The length units are in yards, so the area units will be square yards.
A = 1/2(8 1/2)(3) = (4 1/4)(3) = 12 3/4 . . . . square yards
