Flora is painting her room. Her room is 12 feet by 14 feet . The walls are 9 feet high. On one of the longer walls, there is a rectangular window that is 9 feet by 2 feet. One of the shorter walls has a door that is 6.5 feet by 3 feet. One can of paint covers about 400 sq. feet. If he puts one coat on each wall, how many cans of paint will Flora need to purchase?

    Find the area of the walls, subtract the window and door. That will give the area to be painted. Compare that with 400 to find how many cans of paint.

    Area of the whole thing will be perimeter times height. Area of the window and door will be their height times width. Subtract those from the area of the whole thing and compare to 400.

    Remember, that you can't probably buy a fraction of a can.....

    My solution for your entertainment and edification....LOL Perimeter is 52 times height (9) is about 468. Subtract the area of the window (18) and the area of the door (19.5) to get a total a little more than 400 ft^2. Looks like she might need to get two cans of paint (or at least one and smaller one.....).

    The piece that fits right at the intersection of the wall and the ceiling. Some houses have it, some don't. Usually measured in linear feet (how long the piece is, or pieces total).
