For A, the actual length of Bella's room is 18 feet because I know that the scale will be 1 inch=3feet, so that I just need to find how many feet in 6 inches which is 6 times 3 to get 18 feet. The width is 12 feet because I just take 4 times 3 to get 12 feet. For answer B, the actual area of Bella's room is 216 square feet because I take 18 times 12 to get 216 square feet. Hope it help!
