What is the perimeter of the polygon formed when the points A(-6,6), B(9,-6) and C(9,2) and are graphed and connected with straight lines?
+128475 Distance between B and C = 8
Distance between A and B = sqt [ (-6-9)^2 + (-6-6)^2 ]= sqrt [ 225 + 144 ] = sqrt [ 369 ] = 3sqrt (41)
Distance between A and C = sqrt [ (-6-9)^2 + (6 - 2)^2 ]= sqrt [ 225 + 16 ] = sqrt [ 241]
Perimeter = 8 + 3sqrt (41) + sqrt [241 ] ≈ 42.7
