  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
