    First find the area 72*63

    A=4536

    Then find the area 12*12

    A=144

    Then divide 4536/144

    You would need 31.5 12 by 12in covers to decorate the rectangular region

    As for the 6 by 6

    You would need 126 album covers

    As for the 9 by 9

    You would need 51 covers

    And as for the 15 by 15

    You would need 20.6 covers
