The sides alone are not sufficient to determine uniquely the shape (and hence the area) of a polygon. If you measure one of the diagonals as well, that should be sufficient, provided you label the corners A, B, C, D, state which length applies to which side, and which diagonal the additional length applies to.

Draw a square on a grid. Inset the polygon. Measure the square. Subtract the parts that are not part of the polygon. There is your answer. There is probably a mathmatical formula, but I suspect that is what your teacher expects you to know. I don't do math, so I draw.

Your 4-sided figure is not unique. It can take on various shapes. Therefore it will take on various areas. If you could show that you could shape your quadrilateral so that it can be circumscribed by a circle, then there is a formula to compute the area.

You cant figure this out from the lengths alone. We would need some angles between the sides as well.

Check this site. Without more information, such as an angle, there can be more than 1 solution. Are you asked to find the maximum area? http://mathforum.org/library/drmath/view/54876.html
