Problem 1: Area of triangle
Write a full program that asks the user to input six value that represents the x and y coordinates for three points (x1, y1), (x2, y2), (x3, y3). The three points represent a triangle's corner. Use these values to calculate the area of this triangle, then display the result. The formula for computing the area of a triangle is
SideLength = The square root of the following (x2 - x1)2 + (y2 - y1)2
s = (side1 + side2 + side3) / 2
Area = The square root of the following (s (s - side1)(s - side2)(s - side3) ).
Sample run...
Enter x-coord for the first point: 1.5
Enter y-coord for the first point: -3.4
Enter x-coord for the second point: 4.6
Enter y-coord for the second point: 5
Enter x-coord for the third points: 9.5
Enter y-coord for the third points: -3.4
The area of the triangle is 33.6
