I have 8+ years of experience tutoring math; would love to help you!

Since the ratio is 2:1= length: width

Then the ratio length of the flag is 18cm because you just multiple 9 times 2

So the ratio of the flag is 18:9

Now with a scale factor of 3 you just multiple the ratio by 3

The dimensions of the flag that has a scale factor of 3 is length = 54cm and the width = 27cm.
