3 ft. by 4 ft. because 1/4 inch of an inch is 3ft while 1/3 inch of an inch is 4 ft.

Answer:

The actual dimensions are:

              3 ft by 4 ft  

Step-by-step explanation:

It is given that:

          One inch represents 12 feet.

i.e.   1 inch= 12 feet.

If the bathroom is 1/4 in by 1/3 in on the floor plan.

i.e. the dimensions of the bathroom are: 1/4 inch by 1/3 inch.

Now we know that:

   1/4 inch=12/4 feet

i.e.  1/4 inch= 3 feet.

and

1/3 inch= 12/3 feet

i.e.

1/3 inch= 4 feet

        Hence, the actual dimensions are:

                               3 ft by 4 ft.
