The answer is roughly 103 square feet.
You can get this by first transforming the measurements using the scale factor. To do this, we need to multiply each measurement by 30.
5.5 in * 30 = 165 in
3 in * 30 = 90 in
Now we have the measurements of the room, we can multiply to find the area.
90 in * 165 in = 14850 square inches.
Now to turn this into feet we need to divide by the number of square inches in a square foot (144).
14850 square inches/ 144 = 103 square feet
