units
original
18
8
scaled copy
?
4

Explanation:

Step1: Find the scale factor

The original height is 8, and the scaled copy height is 4. So the scale factor is $\frac{4}{8} = \frac{1}{2}$.

Step2: Apply the scale factor to the original length

The original length is 18. Multiply by the scale factor: $18 \times \frac{1}{2} = 9$.

Answer:

9
