Erin is painting a bathroom along with four walls each measuring 8 ft through 5.5 ft. Ignoring the doors or windows, what is the area to be painted?
The area of the room is the sum of the area of four rectangular walls. Each wall has an area of length times width, or (8)(5.5), which equals 44 ft2. Multiply this through 4 which equal 176 ft2. If you chose c, you added 8 ft and 5.5 ft although of multiplying.
