Use the image to answer the question.

An illustration shows a polygon where the top, right, and bottom sides are perpendicular to each other. A smaller rectangular piece is missing from the center of the left side of the polygon inward. The dimensions are as follows: the top side is 6, the right side is 8, and the bottom side is 6. The left side is divided into three parts. It shows a vertical width of 2 from the top

The area of the figure can be found by adding the areas of the larger polygon and the smaller missing rectangle.

Area of larger polygon = (base + top) x height / 2
Area of larger polygon = (6 + 8) x 6 / 2
Area of larger polygon = 14 x 6 / 2
Area of larger polygon = 84 / 2
Area of larger polygon = 42 square units

Area of missing rectangle = 2 x 6
Area of missing rectangle = 12 square units

Total area = Area of larger polygon - Area of missing rectangle
Total area = 42 - 12
Total area = 30 square units

Therefore, the area of the figure is 30 square units.
