Question

what is the scale factor from the original figure to the scaled copy?
what is the missing length in the scaled copy?

Explanation:

Step1: Determine the scale factor

The scale factor is given as \(2\).

Step2: Calculate the missing length

The original width is \(10\). Using the formula \( \text{Scaled length}=\text{Original length}\times\text{Scale factor}\), we have \(10\times2 = 20\).

Answer:

\(20\)
