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.

The area of the composite figure can be calculated by finding the areas of each rectangle and then adding them together.
Area of the main rectangle = length x width = 7 miles x 3 miles = 21 square miles
Area of the left side rectangle extension = length x width = 6 miles x 3 miles = 18 square miles
Area of the right side rectangle extension = length x width = 1 mile x 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 listed among the options provided.
