given any random point, find the smallest area possible. how?

Question

Given any random coordinates (such as 2,3 or 4,5) in the lower left quadrant, how can you divide a 10x10 piece of property through that random coordinate such that the divided portion has the smallest possible area?

I understand that the formula is (2ab), "a" and "b" being the coordinates, but is there a logical explantion to this?

I've got it! You make a triangle.

But thanks for trying to help, anyways.. =]

Answer 1

Your description is not clear enough to know what you mean... what shape do you make? I'd like to help but need more info :)
