Question

Given : A= 1/2 (B +b)hsolve for h.

Answer 1

The given equation is

`A=(1)/(2)(B+b)h`

First, we multiply each side by 2.

`\begin{gathered} 2A=2\cdot(1)/(2)(B+b)h \\ 2A=(B+b)h \end{gathered}`

Then, we divide the equation by B+b

`\begin{gathered} (2A)/(B+b)=((B+b)h)/((B+b)) \\ h=(2A)/(B+b) \end{gathered}`

Hence, the answer is

`h=(2A)/(B+b)`
