(Geometry: area of a triangle Write a program that prompts the user to enter three points (x1, yl). (x2, y2), (x3, y3) of a triangle and displays its area The formula for computing the area of a triangle is s = (side l + side2 + side3)/2; area = Vs(s-side 1)(s-side2)(s-side3) Here is a sample run: Enter three points for a triangle: 1.5 -3.4 4.6 5 9.5 -3.4 Ener The area of the triangle is 33.6
