Answer
$$h = \frac{2A}{b}$$
The original equation is the formula to find the area of a triangle.
Work Step by Step
To solve this equation for $h$, we need to isolate $h$.
We first divide each side by $\frac{1}{2}$. To divide by a fraction is to multiply by its inverse. The inverse of $\frac{1}{2}$ is $2$:
$$2A = bh$$
We now divide each side by $b$ to isolate $h$:
$$h = \frac{2A}{b}$$
The original equation is the formula to find the area of a triangle.
