A = 1/2 bh can be written as

A = bh/2.

2A = (bh/2)(2)

2A = bh

Divide both sides by h to find b.

2A/h = b

Done.

Let's solve for b.

A=1/2bh

Step 1: Flip the equation.

[tex]\frac{1}{2} bh=A[/tex]

Step 2: Divide both sides by h/2.

[tex]\frac{\frac{1}{2} bh}{\frac{h}{2}}=\frac{a}{\frac{h}{2} }[/tex]

So, the answer for this problem is b=2A/h
