    how to find the area of a triangle given its verticies?

    If a triangle has the verticies A(2,3,7), B(0,-3,4) and C(5,2,-4) how can we determine its area?

    Graph with n verticies

    How many different graphs can be formed with vertex set V= {1,2,3,...,n}? Explain - I there are more than n different graphs. Is there a special formula that can help me?? n^n?? Thanks
