Sorry, Reiny, I copied the 2nd choice incorrectly.
I had posted this problem with you before and the answer given that was not equalalent to A=1/2/bh was
2b =A/h.
The problem is: A = 1/2bh, which is not equivalent?
Choices: 2A =bh, h=2A/b, 2b=A/h, b=2A/h
When I got my test back 2b=A/h was the answer that was not equivalent to A=1/2bh. Did I make a mistake or was their answer incorrect?

you made the mistake 2b=h/A
