The scale factor applied to quadrilateral A to create quadrilateral A is 3/2
What scale factor was applied to quadrilateral A to create quadrilateral A´?
From the question, we have the following parameters that can be used in our computation:
The figures
Where, we have
Figure A and A'
The corresponding ordered pairs on both figures are
A = (1, -1) and (2, 3)
A' = (1.5, -1.5) and (3, 4.5)
Divide the corresponding pairs to calculate the scale factor
So, we have
k = (3, 4.5)/(2, 3)
Using one of the coordinates, we have
k = 3/2
Hence, the scale factor is 3/2
