I have a quadrilateral whose four sides are given

$2341276$, $34374833$, $18278172$, $17267343$ units.

How can I find out its area? What would be the area?

    Unlike a triangle, a quadrilateral is not uniquely defined by its side lengths. For example, if all sides are of unit length, it could be anything from a square with unit area to a very skinny rhombus with area close to zero. You need more information to determine the area, such as the angle between the diagonals, $\theta$ in PEV's answer.2011-01-25
