    The length of the smaller rectangle at the right is 1 inch less than twice its width. Both the dimensions of the larger rectangle are 2 inches longer than the smaller rectangle.

    A=lw

    bigger one is

    A' = (3l) (3W) or

    A'=9lw

    so the bigger one is 9 time of smaller

    8*9=72

    larger is 72m^2
