    I sort of said it wrong it's not slope I always just got to slope be you would use pathegorean theorem for the two sides so 3^2+4^2=c^2 so the length would be root 13 so the perimeter would be root 13 + root 13 +6+6 12+2sqrt13

    i think she got the numbers from the points but used slope intercep form to find the length of the sides

    The length of AB is \(\Large \sqrt{13}\) units long. The same reasoning applies to CD.
