Chapter 2: Programming Project 4 Unlimited tries (Geometry: area of a triangle) Write 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 + side2 + side3)/2 area = square root of s(s - side 1)(s- side2)(s - side3) Sample Run Enter three points for a triangle: 1.5 -3.4 4.6 5 9.5 -3.4 The area of the triangle is 33.6 For a hint on this program, please see https://liangcpp.pearsoncmg.com/cpprevel2e.html.
