The scale factor that thea used to go from rectangle q to rectangle r is; 6
How to work with Scale Factors?
The original rectangle q is missing and so I have attached it.
The length and width of the original rectangle as seen in the attached file are;
Length = 9
Width = 8
Thus;
Area of rectangle r = 9 * 8 = 72 sq.units
Since rectangle q has an area of 2 sq.units, then the area scale factor is;
72/2 = 36
Thus, scale factor in units = √36 = 6
