a room is 24 feet long,18feet wide and 9 feet high. how many square yards of wallpaper are needed to paper the four walls?
Change 24', 18', and 9' to yards.
Then length x width = area in square feet for a wall. That times 4 walls = ??
i really do not get it can you break the problem down a little bettr so i could get better understanding
As DrBob recommended, first change the feet to yards.
24' = 8 yds
18' = 6 yds
9' = 3 yds
Two walls measure 8 by 3. Each of the long walls is 24 sq. m. Two long walls are 48 sq. m.
Now do the same for the short walls.
If you post your answer, we'll be glad to check it.
Ooops -- each of the long walls measures 24 sq. yards (not meters).
How do you Bisect an angle?
To calculate the number of square yards of wallpaper needed to cover the four walls of the room, follow these steps:
1. Determine the perimeter of the room by adding the lengths of all four walls.
Perimeter = 24ft + 24ft + 18ft + 18ft = 84ft
2. Convert the perimeter from feet to yards. Since there are 3 feet in a yard, divide the perimeter by 3.
Perimeter in yards = 84ft / 3ft/yard = 28 yards
3. Calculate the height of the walls that need to be covered by wallpaper.
Height = 9ft
4. Multiply the perimeter in yards (step 2) by the height of the walls (step 3) to find the total square yards needed.
Total square yards = Perimeter in yards * Height = 28 yards * 9ft = 252 square yards.
Therefore, you would need 252 square yards of wallpaper to cover the four walls of the given room.
