it's D proof:

2Ah = 1/b

divide both sides by 2h:
2Ah/2h = 1/b x 2h
simplify

A = 1/2bh

This is an example of algebraic manipulation.

We are given the formula:

A = 1/2bh

Let's see about option A.

In order to isolate b, we need to multiply both sides of the equation by 2 to get rid of the 1/2:

2A = bh

Now we can simply divide both sides by h to isolate b:

2A/h = b

Therefore, A is the correct answer.
