To determine the magnitude of dilation, we can use the formula:
\[ k = \frac{\text{Distance from origin to point after dilation}}{\text{Distance from origin to point before dilation}} \]
In this case, I cannot see the image, so I recommend looking at the coordinates of points A, B, C, and D and their corresponding dilated points A′, B′, C′, and D′. Measure the distances from the origin to each point before and after dilation, then apply the formula to find the value of \( k \).
If you know those distances, you can easily plug them into the formula to find the magnitude of dilation. If you have any specific coordinates or additional parameters of the points, please share, and I can help you compute it!
