If the scale factor from a small figure to a large figure is given as a percent, how can you find the side lengths of the large figure from the side lengths of the small figure?

PLEASE HELP ME!!!

PLEASE HELP!!!!! THIS IS SOOOOO CONFUSING AND MY TEACHER NEVER REALLY EXPLAINED IT TO ME.

First change the % into decimal form.
If the large figure is 10% larger, it is 0.10 larger.
So, small side length plus 0.10x small side length would = large side length.
