Marcia developed a roll of film and received 4inch by 6inch prints. She wants to have one picture enlarged to an 8inch by 12inch print. What kind of transformation is this? What is the scale factor?

8/4=2
12/6=2
Area of first rectacangle:
A1=4*6=24
Area of second rectacangle:
A2=8*12=96
96/24=4
Scale for dimensions 2
Scale for areas 4
