Question

could someone help me find the area on these? you can do just one, but i’d prefer #10 to be done! ty!!

Answer 1

7.5

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
