2.19 (Geometry; area of a triangle) Write a program that prompts the user to enter three points, (x1, y1), (x2, y2), and (x3, y3), of a triangle then displays its area The formula for computing the area of a triangle is s (sidel +side2 + side 3)/2 area = Vs(s-side IXs-side2)(s-side3) Here is a sample run Enter the coordinates of three points separated by spaces like x1 y1 x2 y2 x3 y3: 1.5-3.4 4.6 5 9.5-3.4 The area of the triangle is 33.6
