#### 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
