Question

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

Answer 1

we have the formula

$A=\frac{1}{2}bh$

Solve for h

that means ----> isolate the variable h

so

Step 1

Multiply by 2 on both sides

$\begin{gathered} A*2=\frac{1}{2}bh*2 \\ 2A=bh \end{gathered}$

Step 2

Divide by b on both sides

$\begin{gathered} \frac{2A}{b}=\frac{bh}{b} \\ \\ \frac{2A}{b}=h \\ \\ h=\frac{2A}{b} \end{gathered}$
