Scale factor = 0.4
Step-by-step explanation:
Parallelogram EFGH is similar to Parallelogram JKLM
EF corresponds to JK
FG corresponds to KL
GH corresponds to LM
HE corresponds to MJ
scale factor = new length/old length
We are moving from EFGH to JKLM
JKLM = new image, EFGH = old image
Scale factor = JK/EF
Scale factor = 11.2cm/28cm = 0.4
OR
Scale factor =MJ/HE = 5.6cm/14cm = 0.4
Scale factor = 0.4
