Question

this question is about increase in the side of the square and what is increase in percentage

Answer 1

2:3 is the "before to after" ratio, if the side increases its length.  The increase is 1, based on a starting value of 2, so the increase is 50%. 

 

(The new size is 150% of the original length.)
