Answer:
The answer is the last choice, h= 2a/b
Step-by-step explanation:
If you take the original equation, a=1/2bh, you can first divide each side of the equation by 1/2, this would give you 2a = bh. Next you would divide each side of the equation by b to solve for h. This would give you h= 2a/b, which is your final answer.
