(Geometry: area of a triangle) Write a program that prompts the user to enter three points (x1,y1),(x2,y2), (x3,y3) of a triangle and displays its area. The formula for computing the area of a triangle is: s=( side 1+ side 2+ side 3)/2 area = square root of s(s - side )(s - side 2)(s - side 3) Sample Run Enter three points for a triangle: 1.53.44.659.53.4 The area of the triangle is 33.6
