The sides of the composite figure 1 mi 1 mile 1 mile 3 miles 6 miles 7 miles

What is the area of the composite figure
31 square miles
21 square miles
28 square miles
25 square miles

To find the area of the composite figure, we first need to calculate the area of each individual shape separately, then add them together.

Area of the rectangle = length x width
= 3 miles x 6 miles
= 18 square miles

Area of the triangle = 1/2 x base x height
= 1/2 x 1 mile x 7 miles
= 3.5 square miles

Total area of the composite figure = 18 square miles + 3.5 square miles
= 21.5 square miles

Therefore, the closest option to the area of the composite figure is 21 square miles.
