## perfectionist 3 years ago 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?

anyone, plz?

2. AnimalAin

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.

3. AnimalAin

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.

kk, thank you :)

5. AnimalAin

What did you figure out?

6. perfectionist

still workin on it!

7. AnimalAin

Faster!! It's getting late!

8. perfectionist

I got 430.5 sq. ft, now just gotta divide by 400 to get final ans.

9. AnimalAin

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

10. perfectionist

right, so instead of 1.1, it'll b 2.

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.....).

okay. thank you. just one quick question: what's crown molding? (Its for another one of my questions)

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).

14. perfectionist

okey dokey. thanks again. :D

No sweat.
