Answer 1

30.6 + 49.6

80.2 in²

Answer 2

B. 80.2 square inches

Explanation:

This figure is a composite figure made up of two rectangles (see attachment).

The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.

In the top rectangle, the length is 3 and the width is 10.2, so A = 3 * 10.2 = 30.6 square inches.

The length of the bottom rectangle is 8 and the width is 6.2, so the area is A = 8 * 6.2 = 49.6 square inches.

Add these together: 30.6 + 49.6 = 80.2 square inches.
