Answer:

7.5

Step-by-step explanation:

9.  So we know the length of a rectangle is the length * width.

The width of each of the triangles is 1 (difference in x-value).  And the height is the point on the graph that it is touching.  

The height (y value) of the rectangles are 1, 2, 2, 2, 1/2

So the area of the rectangles will be:

(1+2+2+2+1/5)1 = 7.5
