Question 164500
I'll do the equation.

Solve for h.

A = 1/2 (bh)

We can write 1/2 (bh) like bh/2 for easy reading.  They both mean the same thing.

We now have A = bh/2

Multiplying both sides of the equation by 2 and we get:

2A = bh

To solve the equation for h, we want to get h alone.

To do so, divide both sides of the equation by b.

2A/b = h
