Question

Calculate the area of the composite figure.

A. 125.0
B. 144.0
C. 145.0
D. 165.0

Answer 1

C - 145

Explanation:

This figure can be split into a trapezoid and a rectangle.

The rectangle has dimensions 7 x 11, and the trapezoid has bases of 11 and 6, and a height of 8 (15-7).

The area of the figure is the area of the rectangle + the area of the trapezoid, which is 7*11 + (11+6)/2 * 8 --> 77 + 17*4 --> 77+68 --> 145. The answer is C
