Math Problem Statement

The rectangle F'G'H'I' is a dilation of the rectangle FGHI. What is the scale factor of the dilation?

Solution

The problem involves determining the scale factor of the dilation between two rectangles FGHIFGHI and FGHIF'G'H'I'.

Step-by-step Solution:

  1. Locate the Coordinates of Rectangle FGHIFGHI (the original rectangle):

    • F=(2,2)F = (2, -2)
    • G=(4,2)G = (4, -2)
    • H=(4,4)H = (4, 4)
    • I=(2,4)I = (2, 4)
  2. Locate the Coordinates of Rectangle FGHIF'G'H'I' (the dilated rectangle):

    • F=(6,6)F' = (6, -6)
    • G=(12,6)G' = (12, -6)
    • H=(12,12)H' = (12, 12)
    • I=(6,12)I' = (6, 12)
  3. Check the Dilation Formula: The scale factor of dilation is calculated by comparing the distances between corresponding points on the two rectangles.

    • Distance between FF and GG in the original rectangle: FG=42=2FG = 4 - 2 = 2
    • Distance between FF' and GG' in the dilated rectangle: FG=126=6F'G' = 12 - 6 = 6
  4. Calculate the Scale Factor: The scale factor kk is given by: k=Distance in dilated figureDistance in original figure=62=3k = \frac{\text{Distance in dilated figure}}{\text{Distance in original figure}} = \frac{6}{2} = 3

So, the scale factor of the dilation is 3.
