To find the area of the composite figure, we need to find the area of the rectangular region and the area of the triangular region, and then add them together.
Area of rectangular region:
Length = 9 miles
Width = 4 miles
Area = Length x Width = 9 miles x 4 miles = 36 square miles
Area of triangular region:
Base = 9 miles
Height = 4 miles
Area = (0.5) x Base x Height = (0.5) x 9 miles x 4 miles = 18 square miles
Total area of the composite figure:
36 square miles (rectangular region) + 18 square miles (triangular region) = 54 square miles
Therefore, the area of the composite figure is 54 square miles.
So, none of the provided responses are correct.
