Answer:

The area is 14 inches squared.

Explanation:

To find the area of a trapezoid the equation is...

a+b

------ x h (a and b equal the bases)

2

Seeing as we know all of the basses and heights lets plug it into the equation.

9+5

------- x 2

2

Well the 2 and the 2 cancel each other out in this scenario so what we would have to do now is ad 9 and 5 which would get us to 14.
