Answer 1

Explanation:

Answer 2

The calculated area of the shaded region is 81 square feet

Hwo to determine the area of the shaded region

From the question, we have the following parameters that can be used in our computation:

The figure

The area of shaded region is calculated as

Area = Area of big rectangle - Area of triangle

Using the above as a guide, we have the following:

Area = 10 * 9 - 1/2 * 6 * 3

Evaluate

Area = 81

Hence, the area of the shaded region is 81 square feet
