I know that I posted this question last week or something, I couldn't find it so I am reposting this question again.
geez, and you didn't solve it during that time?
I saw at least one response which did it, so here it is
A = (a+b)h/2
2A = (a+b)h
2A = ah + bh
2A - ah = bh
(2A-ah)/h = b

how did you get 2A
He multiplied both sides by 2 to get rid of the 2 in the denominator.
