Question

What is the area of the triangle in the composite figure above?

A. 5 in
B. 10 in
C. 20 in
D. 65 in

Answer 1

The correct answer is C. 20 in. To calculate the area of the triangle, we can use the formula A = 1/2 bh. The base of the triangle is 10 in and the height is 8 in, so the area is 1/2 x 10 x 8 = 40 in^2. Since the triangle is a right triangle, the area is half of 40 in^2, which is 20 in^2
