Formula for the area of a trapezoid:
0.5 x h x (b + a)
b = 6 + 3 + 3 = 12
h = 8
a = 6
0.5 x 8 x (12 + 6)
4 x 18 = 72
A = 72 square units
D I hope this really helps a lot

<em>Additional comment</em>
We notice the differences between these numbers are the same: 10. The only right triangle with side lengths having the same difference is some multiple of a 3-4-5 right triangle. For a right triangle with side lengths having a difference of 10, the sides would have to be 30, 40, 50--not 10, 20, 30.
