Brain Teasers
Arriving at the Area
Ramona's parents have promised her a beautiful new blue carpet for her room. All she has to do is figure out how many square feet her room is.
Ramona measures her room with a tape measure. It is 9 ft 6 in. long and 7 ft 3 in. wide. In one of the longer sides is an alcove, 4 ft wide and 2 ft deep, where Ramona keeps her horse collection on shelves. On the opposite side, the radiator stands in front of the wall. It is 15 in. deep and 27 in. wide. The carpet can't go under it. As long as she is carpeting the room, Ramona has decided to put a piece of carpet on top of her built-in dresser. The dresser covers the floor and sticks out 18 in. from one of the short walls and is 32 in. wide.
How many square feet of carpet does Ramona need for her room, to the nearest whole square foot?

Hint
Rewrite the inches as decimal fractions of a foot.Answer
Room's area: 9.5ft*7.25ft=68.88sqftAlcove's area: 4.0ft*2.0ft=8.00sqft
radiator's area: 1.25ft*2.25ft=2.81sqft
68.88+8.00-2.81=74.07
Rounding up to the nearest whole number, Ramona needs 75 square feet of carpet. There is no carpet underneath the built-in dresser, so carpeting its top doesn't add to or subtract from the room's area.
