Answer
We see that the statement is false.
To make the statement true, we change the statement so that $2$ is in the numerator and not the denominator:
If $A = \frac{1}{2}bh$, then $b = \frac{2A}{h}$.
Work Step by Step
We want to solve for $b$ in this problem, so we need to isolate $b$.
First, we divide each side by $\frac{1}{2}$, which means we multiply by its inverse, which is $2$:
$$2A = bh$$
Now, we divide each side by $h$:
$$b = \frac{2A}{h}$$
We see that the statement is false. To make the statement true, we change the statement so that $2$ is in the numerator and not the denominator:
If $A = \frac{1}{2}bh$, then $b = \frac{2A}{h}$.
