Step-by-step explanation:
Answer: 2 enlargments
Step-by-step explanation:
Use proportion for each enlargment you do
Side a=6cm Side b=4cm
6:4=x:7 4:4=b1:7
7*6=4a1 b1=28/4
a1=42/4 b1=7 after first enlrge
a1=10.5 after first enlarge 7:4=b2:7
10.5:4=a2:7 b2=49/4
a2=73.5/4 xb2=12.5 after 2nd enlarge
a2=18.375 after 2nd enlarge
12.5:4=b3:7
18,375:4=a3:7 b3=21.875 cm after 3rd enlargement
a3=32.15after 3rd enlargement
Values after 3rd enlargement are higher than dimension given for picture wall
30 cm by 20 cm
