    So assuming that the only had 3+6=9 tiles

    what we have to do it find teh area total

    area=legnth times width

    3 tiles are 3 and 1/2 times 3

    3 times 3 and 1/2=10 and 1/2

    times 3 tiles

    10 and 1/2 times 3=31 and 1/2 squar inches

    6 tiles are 4 by 3 and 1/4

    4 times 3 and 1/4=13

    6 tiles times 13 inchessquare=78

    so we add

    31 and 1/2+78=109 and 1/2 square inches
