The scale factor of the dilation applied to the quadrilateral is S = 4.
What is the scale factor of the dilation?
The scale factor of the dilation is given by the quotient between the length of one of the sides of the dilated figure and the length of the correspondent side of the original figure.
If we select the top side, the length on the dilated figure is 72 inches, and the length of that side on the original figure is 18 inches, then the scale factor of the dilation is given by:
S = 72in/18in = 4
The scale factor is 4.
