Question

Solve the formula for the indicated variable.Area of a triangle: A=1/2bh; solve for h.

Answer 1

we have the formula

`A=(1)/(2)bh`

Solve for h

that means ----> isolate the variable h

so

Step 1

Multiply by 2 on both sides

`\begin{gathered} A*2=(1)/(2)bh*2 \\ 2A=bh \end{gathered}`

Step 2

Divide by b on both sides

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