Question

choose the correct scale factor:

Explanation:

Step1: Determine the length of corresponding sides

Assume the original figure has a side length (e.g., horizontal side of the smaller - like part) and the new figure has a corresponding side length. Let's say the original side length (from the grid) is \(3\) units and the new side length is \(6\) units.

Step2: Calculate the scale factor

The formula for the scale factor \(k\) is \(k=\frac{\text{new length}}{\text{original length}}\). If new length \(L_{new} = 6\) and original length \(L_{old}=3\), then \(k = \frac{6}{3}=2\)

Answer:

\(2\)
