Use the image to answer the question. What is the area of the composite figure? (1 point) Responses 31 square miles 31 square miles 21 square miles 21 square miles 25 square miles 25 square miles 28 square miles 28 square miles
The area of the composite figure can be calculated by first finding the area of the rectangle and then subtracting the area of the triangle.
Area of rectangle = length x width = 5 miles x 7 miles = 35 square miles
Area of triangle = 0.5 x base x height = 4 miles x 3 miles x 0.5 = 6 square miles
Therefore, the total area of the composite figure is 35 square miles - 6 square miles = 29 square miles.
So, the closest option to the actual area of the composite figure is 28 square miles.
