    Can you use that information to set up the two equations you need?

    Woah. Well, "The length is thrice the width" --> L=3W.

    "Perimeter is 56" --> 2L+2W=56.

    Sub the first equation into the second to solve for W.

    18 and 6 won't get you a perimeter of 56.

    Excellent. Now you can just count over and down from the given point to find all the other coordinates.

    yeah!! But when I try to use the distance formula!!! Im getting two second degree equations!! How m I suppose to solve them when ive got two equation something like ax^2+b^y2+cx+dy+e=0

    Forget about the distance formula! Just count.

    The distance formula is so overrated. It is merely the pythagorean theorem, but when you have horizontal and vertical lines, you don't need to solve for a hypotenuse.

    then?? Should I just put in simple increment formula and solve??

    No formulas, no solving - elementary arithmetic.
