The problem of extension is too much interesting for bipartite graph since there is a specialty for keeping the properties of this graph. This paper presents a study on the extensive of bipartite graphs with finite number of vertices. Some examples of extensive bipartite graphs and a counter example of Inextensive bipartite graphs are given. This counter example is a generalization for many bipartite graphs.
