Write a C program that computes the area of a triangle. Proceed as follows.

• Read the x and y coordinates of the three vertices of a triangle.
• Compute the lengths a, b and c of the three sides of the triangle.
• Compute the semiperimeter s = (a + b + c) / 2.
• Compute the area A = [s (s - a) (s - b) (s - c)]^1/2.
• Print the area A.

Report the output of your program on the following inputs.

• (3,8), (4,2), (5,9)
• (-1.1,-1.1), (2.2,-3.3), (-4.4,5.5)
• (-2,9), (3,4), (8,-1)
