Question

What is the area of the unshaded part of the following composite figure? Round your answer to the nearest tenth.

a. 77.8

b. 59.6

c. 18.2

d. 63.0

Answer 1

I think the answer is C. 18.2

Answer 2

It’s B. Multiply the triangle and subtract the rectangle. 15.1 x 10.3 / 2 = 77.765. 2.8 x 6.5 = 18.2. 77.765-18.2= 59.565 = 59.6
