find the perimeter of a triangle whose vertices are the followinf specified points in the plane?

(9,-1)(-9,7)and(4,3)

  • math -

    The sides have lengths

    √(18^2 + 8^2) = √388
    √(5^2 + 4^2) = √41
    √(13^2 + 4^2) = √185

    Not much can be done to simplify that, so just add them up. The total is approx. 39.7
