Help me with this question on composite solids

21 + 70 + 17.5 = 108.5,  B is your answer

6 x 7 = 42

7 x 5 = 35 divided by 2 = 17.5

7 x 10 = 70

Add them all up to get 108.5

B. 108.5 ft²

Step-by-step explanation:

The shape is split up into 2 triangles and a rectangle. Find the area of those shapes then add them up in the end.

A(Right triangle) = 1/2(6)(7) = 21 ft²

A(Rectangle) = (7)(10) = 70 ft²

A(Left triangle) = 1/2(7)(5) = 17.5 ft²

A(Shape) = 21 + 70 + 17.5 = 108.5 ft²

is only a line? i think so
