Answer 2

Explanation:

This problem bothers on the mensuration of flat shapes, composite rectangle.

The correct method for finding the area of a composite rectangle with a large rectangle and a small rectangle connected on the right side are highlighted below.

also see attached the rough sketch of the two rectangles.

1. Decompose the figure into two rectangles and add the areas
2. Extend the top and rightmost sides to make a larger rectangle, find its area, and then subtract the area of the removed corner.
3. Decompose the figure into two rectangles, find their sum, and then subtract the area of the removed corner.
