Multiply both sides by 2 to get rid of the fraction on the right side:

[tex]2A = bh[/tex]

Divide both sides by h to get b by itself. The following expression will be your answer:

[tex]\boxed{\frac{2A}{h} = b}[/tex]
[tex] A = \frac{1}{2} bh[/tex]
Multiply both sides by 2.

[tex]2A=bh[/tex]
Divide both sides by h.

[tex] \frac{2A}{h} = b[/tex]; flip it around:
[tex]\boxed {b = \frac{2A}{h}} [/tex]
