Answer:
1/3
Step-by-step explanation:
If you divide one of the sides in figure A by 3, then you will get the corresponding side for figure B.
So if I divide the uppermost side, which is 33units by 3, I will get the uppermost side in figure B, which is 11units.
Since dividing b 3 is like multiplying by 1/3 then the scale factor is 1/3
