Question

I got to have some help on this question...

Answer 1

12 inches is the length of the larger square's side

Answer 2

I was going to try to do it some fancy equation way, but i couldn't seem to manipulate any of my equations just the right way. 


But.....I did come across the answer by chance while testing something in my calculator.

so, if y is the length of the original side of the square and x is the new length:
x+2=y

4x=perimeter of original square
4x=10+y
or
4x=10+(x+2)

I plugged 4 into this by chance and look what we have from that:
4x=10+(x+2)
4•4=10+(4+2)
16=10+6
16=16
Bingo!!! it's a match!

so the new length of one side is 6 inches.
