Answer: Area=35km^2
Explanation:
You need to find the areas of the rectangle and then the triangle.
First, you start with splitting up the figure to a rectangle and a triangle.
Secondly 6*5= 30 so the area of the rectangle is 30 km.
Thirdly, you add that to the area of the triangle, which you figure out because the opposite side of the figure is 6 km so the remaining length is going to be 2km. The area of a triangle is (1/2)(Base)(Height), so (1/2)(5)(2)= 5.
Add the 30 with the 5 and you get a total of 35 km for the area.
