Explanation:

Step1: Determine the scale factor

The original length is 90 and the scaled length is 30. So the scale factor is $\frac{30}{90}=\frac{1}{3}$.

Step2: Apply the scale factor to the original height

The original height is 45. Multiply by the scale factor: $45\times\frac{1}{3} = 15$.

Answer:

15
