  4. Okay, do you know anything about D, E or F? Or, do we just assume they are points that could be anywhere on the plane?

  5. Since E and F are the midpoints of their sides, we are talking about medians of a triangle.

    The medians meet 2/3 of the way from the vertex to the side.

    So,
    AD/DF = 2
    CD/DE = 2

    AD x CD/DF x DE = AD/DF * CD/DE = 4
