Answer:
100m^2
Step-by-step explanation:
area of trapezoid formula: 
b=base
so
base #1= 8
base #2= 12
h(height)= 10
(8+12)=20(sum of bases)
20/2=10(sum of bases over 2)
10*10=100(height * whats remaining of bases)
100m^2
hope this helps

From there we can see that because x equals both to a and b, it must be that a = b.
