Homework Help: Vectors forming a parallelogram

  1. Nov 20, 2007 #1
    The vectors 39.0 cm at 15.0° and 23.0 cm at 68.0° both start from the origin. Both angles are measured counterclockwise from the x axis. The vectors form two sides of a parallelogram.

    a) Find the area of the parallelogram.
    716cm^2

    b) Find the length of its longer diagonal.

    For b) is this question looking for the unknown length?

    **update**
    I found the answer

    The wording you posted is odd since both diagonals of a parallelogram are equal. ARe you sure you copied the problem correctly?
