# How do you solve for h in a=1/2bh?

Dec 26, 2016

$b = \frac{2 a}{h}$

#### Explanation:

rearrange by applying inverse operations.

$a = \frac{1}{2} b h$

multiply both sides by $2$

$2 \times a = \cancel{\frac{1}{2} \times 2} b h$

$2 a = b h$

divide both sides byb

$\frac{2 a}{h} = b \cancel{\frac{h}{h}}$

$b = \frac{2 a}{h}$
