Calculate area for a classical problem

[pankaj tiwary]

I have a problem and I am not able to get the solution for that. So, I
thought may be you people can help me out.

The problem is I have 3 arrows and each one of them has got
intrincically 3 sub-arrows for which the co-ordinates are known. That
means one arrow in turn releases 3 sub-arrows who hit at certain point
on the ground and the area of the traingle formed by the three
sub-arrows is burnt out. This way I have 3 arrows and so 3 traingles.
The problem is how to find out the total area burnt by the 3 arrows.

I hope I am clear to all of you. The problem I face in in determining
the area which may be common to 2 traingles. Please help me in this
regard.

This is a math problem more than it is a C language question.

The answer to your question is:
Total area = Area1 + Area2 + Area3.

Research out how to find the area of a triangle, given
three points. I recommend posting to a group with "sci.math"
in its name.
