What is the total area of the figure below?

The total area of the figure is 141 in^2.
To find the area of this figure you need to separate it into different sections.

First to find the area of the triangle on the left is multiple 8 by 3, giving the area of 24.

Second find the area of the rectangular shape towards the left, and ignore the triangle ends on both sides for now. To find the area of the rectangle multiply 10 by 9.

Lastly, to find the area of both triangles on both ends is to multiply 9 by 3. The three is found by subtracting 10 from 16 and dividing it by two.

Adding all the areas together gives you the answer = 141 in^2

Yes, two vertical lines can be complementary
