    New area is 175 42/45 feet ²

    Step-by-step explanation:

    Given data

    Length l = 15 1/4

    To proper fraction = 61/4 feet

    Width w = 8 11/15

    To proper fraction = 131/15 feet

    Extention = 1 2/3

    To proper fraction = 5/3

    Dimensions of new rectangle

    Length = 61/4+5/3 = 183+20/12

    LCM = 12 = 203/12

    Width = 131/15+5/3 = 131+25/15

    LCM = 15 = 156/15

    Area = 203/12*156/15 = = 31668/180

    =31668/180

    = 7917/45

    = 175 42/45 feet ²
