If the area of a triangle is given, then both positive and negative values of the determinant are used for calculation.why?
Determinant can have both positive and negative values, but area is always positive.
Consider a simple example:
Let us find the coordinate of a missing point of a triangle, when the area is known.
Let A(-2,2);B(1,5) and C(x,-1) be the three coordinates and area of the triangle =16.5
