Question

A= 1/3BH solve for B

Answer 1

The given formula is

`A=(1)/(3)\cdot B\cdot H`

First, we multiply the equation by 3.

`\begin{gathered} 3A=3\cdot(1)/(3)\cdot B\cdot H \\ 3A=B\cdot H \end{gathered}`

Then, we divide the equation by H

`\begin{gathered} (3A)/(H)=(B\cdot H)/(H) \\ (3A)/(H)=B \end{gathered}`

Therefore, the solution to B is

`B=(3A)/(H)`
