what is the perimeter of triangleABC if the coordinattes of A,B and C are (3,7), (7,3) and (-2,5) respectively
Add the distances between the three pairs of points:
AB = sqrt[(-4)^2 + 4^2] = 5.657
AC = sqrt[5^2 + 2^2] = 5.385
BC = sqrt[5^2 + (-2)^2] = 5.385
sum = 16.427
You't better check my numbers.
