What is the perimeter of the polygon formed when the points A(-6,6), B(9,6) and C(9,-3) are graphed and connected with straight lines?

Plot the points.....connect the points....

   a right triangle     base = 15   ( from -6 to +9)   height = 9   (from 6 to -3)

      

    calculate the hypotenuse with pythagorean theorem ......or use the distance formula ...then add all of the sides
