Answer:
7.5
Step-by-step explanation:
<em>To find the area of a trapezoid it is:</em>

<em>Where h is the height, b is the base, and a is the "top base," so our values are:</em>
h = 5
b = 9
a = 6
<em>Plug them in and solve:</em>





<em>The area of the rectangle is found by using:</em>
where b is the base and h is the height. So our values are:
b = 6
h = 5
Plug in and solve:



<em>Subtract the rectangle from the trapezoid:</em>
37.5 - 30 = 7.5
Answer: 7.5
Hope this heps, have a nice day :D
