Opener:

  • Suppose that you receive a new colored rectangle called “GREEN C”, and you measure its sides.  You find that the length of GREEN C is 7.2 cm, and the width of the rectangle is 9.9 cm.

    1. How long do you expect the diagonal of this rectangle to be?

    2. What angle will the diagonal make with the bottom of the rectangle?
