Solve for b A=1/2b*h

$A = \frac{1}{2} b \cdot h$

Rewrite the equation as $\frac{1}{2} b \cdot h = A$ .

$\frac{1}{2} b \cdot h = A$

Divide each term in $(\frac{1}{2} b \cdot h) = A$ by $\frac{1}{2} h$ and simplify.

Divide each term in $(\frac{1}{2} b \cdot h) = A$ by $\frac{1}{2} h$ .

$\frac{(\frac{1}{2} b \cdot h)}{\frac{1}{2} h} = \frac{A}{\frac{1}{2} h}$

Simplify the left side.

Cancel the common factor of $\frac{1}{2}$ .

Cancel the common factor.

$\frac{\frac{1}{2} b \cdot h}{\frac{1}{2} h} = \frac{A}{\frac{1}{2} h}$

Rewrite the expression.

$\frac{b \cdot h}{h} = \frac{A}{\frac{1}{2} h}$

Cancel the common factor of $h$ .

Cancel the common factor.

$\frac{b \cdot h}{h} = \frac{A}{\frac{1}{2} h}$

Divide $b$ by $1$ .

$b = \frac{A}{\frac{1}{2} h}$

Simplify the right side.

Combine $\frac{1}{2}$ and $h$ .

$b = \frac{A}{\frac{h}{2}}$

Multiply the numerator by the reciprocal of the denominator.

$b = A \frac{2}{h}$

Combine $A$ and $\frac{2}{h}$ .

$b = \frac{A \cdot 2}{h}$

Move $2$ to the left of $A$ .

$b = \frac{2 A}{h}$
