Area of a Parallelogram with out cross products

  1. Oct 9, 2008 #1
    1. The problem statement, all variables and given/known data

    given the vertices:
    (0,0)
    (3,1)
    (2,3)
    (5,4)
    2. Relevant equations

    solving without cross products and with mathematica if available


    3. The attempt at a solution

    Te1=[3]
    [1]
    Te2=[2]
    [3]


    [det[Ay]]
    ________

    [det[A]]

    get you the solution

    i got 7

    correct?
