Awesome that helps. So the area for a trapezoid uses the equation: 
[A = \frac{ a+b }{ 2 }h\]
a and b are the bases, in this case 8 and 11. The order doesn't matter, I'll just say a=8 and b=11.
the height is 4. 
(this may seem kind of backwards, but if you imagine rotating the trapezoid it makes sense).
So plug in your numbers to get your answer:
[(8+11)/2]4 = 38
does that make sense?
