In order to determine the area, we need a fixed form  that is, the shape cannot change. That means we need to know the lengths of the diagonals (so that we can break the shape down into triangles) or the angles at the corners. When we have the lengths and the angles, we can determine the area. Many people make the incorrect assumption that area is based only on the lengths of the sides, but you can see now that more information is needed. Penny Nom and Stephen La Rocque.
