Question: Write a program that prompts the user to enter three points ( x 1 , y 1 ) , ( x 2 , y 2

Write a 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 =(side1+ side2+ side3)/2
area = square root of s(s - side1)(s - side2)(s - side3)
