  • geometry -

    Think of the rhombus as a rectangle where the lines joining the mid-points are the diagonals of the rhombus.

    The area of a rhombus is therefore half of product of its diagonals.
    So 15*D/2=165.
    Solve for D.

  • geometry -

    A Area

    AC and BD diagonals




    330=15*BD Divide with 15


    go to wikipedia and type rhombus
