Explain why it is possible to draw more than two different rectangles with an area of 36 square units, but it is not possible to draw more than two different rectangles with an area of 15 square units. The sides of the rectangles are whole numbers. EXPLAIN your answer.

  1. factor pairs of 36:
    1 36
    2 18
    3 12
    4 9 ---- so I could draw 4 different rectangles of area 36 with whole number sides

    factor pairs of 15
    1 15
    3 5 ---> only 2 possible
