Final answer:
The scale factor from rectangle JKLM to rectangle WXYZ is 3/4.
Step-by-step explanation:
The scale factor is determined by comparing the corresponding sides of the two rectangles. In rectangle JKLM, JM is 9 centimeters and JK is 12 centimeters. In rectangle WXYZ, WX is 18 centimeters and WZ is 13.5 centimeters. By dividing the corresponding side lengths, we find that: JM/JK = WX/WZ.
Substituting the values, we have 9/12 = 18/13.5.
Reducing the fractions, the scale factor is 3/4.
