Question

A=1/2(bh) solve for b

Answer 1

First, we should get rid of the 1/2, so we can multiply by 2.
This will give you 2A=bh.
Now you just divide by h, and then there's your answer.
b=2A/h

Answer 2

Divided each side by h and, divide by 1/2 and then simplify.\[b=\frac{2 A}{h} \]

Answer 3

\(\huge A = \frac{bh}{2} \rightarrow \color{red}{\frac{2}{h}} \times A = \frac{bh}{2} \times \color{red}{\frac{2}{h}}\)
