Answer

Explanation:

Step1: Substitute given values into formula

Given $A = 30$, $b=12$ and $A=\frac{1}{2}bh$, we get $30=\frac{1}{2}\times12\times h$.

Step2: Simplify the right - hand side

$\frac{1}{2}\times12 = 6$, so the equation becomes $30 = 6h$.

Step3: Solve for h

Divide both sides by 6: $h=\frac{30}{6}=5$.

Answer:

B. 5 units
