1. Sketch it out :)
One side is 3 shorter then the other, so you need x + 3 to reach the x side. The other side is x - 2, and the other side is x.
P = s + s + s
28 = x + x - 2 + x + 3

3. Third Side>First Side>Second Side
x-2>x>x+3
x+x+x+3+-2=3x+1
28-1=27
27/3=9
x=9
x+3=12
x-2=7
Answer: Third Side=7 First Side=9 Second Side=12
