The lengths of the sides of any irregular polygon, other than a
triangle, does not provide enough information to determine its
area. This is because polygons with 4 or more sides are not
rigid.
Every question is just a happy little opportunity.

If you mean as in an irregular 4 sided quadrilateral then such a
shape is impossible to construct from the given dimensions and so
finding its area can't be evaluated.
