Rearrange to make $h$ the subject:
\[
A=\frac{1}{2} \times b \times h
\]
\(\boxed{h = \frac{2A}{b}}\) is the final answer.
Step 1 :Rearrange the formula to make \(h\) the subject: \[A=\frac{1}{2} \times b \times h\]
Step 2 :Isolate \(h\) on one side of the equation: \[h = \frac{2A}{b}\]
Step 3 :\(\boxed{h = \frac{2A}{b}}\) is the final answer.
