Use the image to answer the question.
An illustration shows a rectangle extending upward on the top left and top right sides forming two more rectangles of varying width and length. The dimensions are as follows: The bottom of the rectangle is 7 miles. The extended left side is 6 miles. The vertical height of the left side rectangular extension is 3 miles. The vertical and horizontal lengths of the right side rectangular extension is 1 mile each. There are six right angle symbols at the vertices of the polygon.

To find the area of the composite figure, we need to find the area of each individual rectangle and then add them together.
Area of the main rectangle: 7 miles * 3 miles = 21 square miles
Area of the left side rectangular extension: 6 miles * 3 miles = 18 square miles
Area of the right side rectangular extension: 1 mile * 1 mile = 1 square mile
Total area = 21 square miles + 18 square miles + 1 square mile = 40 square miles
Therefore, the correct answer is not provided in the options given. The closest option is 31 square miles, but the correct area is 40 square miles.
