If Two Polygons Are Similar, How Can You Find The Scale Factor From One Polygon To The Other?

By dividing the larger side number by the smaller side number
thanked the writer.
The scale for similar figures is equal to the ratio of similitude.
Suppose there are 2 rectangles, ABCD and A`B`C`D`.
Suppose that AB = 6cm and BC = 4cm, and
A`B` = 3cm and B`C` = 2cm.
Ratio of simplitude can be calculated by taking the ratio of corresponding sides of similar figures.
AB:A`B`
6:3
2:1
By looking at the ratio, it is possible to tell that rectangle ABCD is twice the size of A`B`C`D`
and rectangle A`B`C`D` is half of ABCD.

I think this should be more explained so if a kid is trying to do there homework and need help with this qustion then they get help.
To everyone who answered this question about the scale factor, thank you! I am learning this in math right now, and for some reason, it is really confusing to me. I have to finish my math test, and there was a problem on there about what the scale factor was (A= 3 and B=6) and I put 2 because A is twice the size of B (3,6) and I was checking to see if the method I was using was correct.
