    We can put the dimensions of Mary's garden into ratio format:

    6ft by 8ft = 6ft : 8ft

    Now if she increased it by a scale factor of 2=

    6ft : 8ft = __ : 16ft

    So we can see that 8 was multiplied by 2, so we do the same for 6:

    6ft : 8ft = 12ft : 18ft.

    So the measurements should be 12ft by 16ft
