natasha is painting her bedroom, which measures 15 feet by 12 feet and has an 8-foot ceiling. not accounting fo windows and doors, how many square feet will she be painting?
Assuming she is only painting the 4 walls
Area = 2(12x8) = 2(15x8) = 552 square feet
If she also paints the ceiling , add on 15x12 square ft
If she's not painting the ceiling --
2 (15 * 8) + 2 (12 * 8) = ?
To calculate the number of square feet Natasha will be painting, you need to find the total area of the walls in her bedroom. To do this, you need to find the perimeter of the room and multiply it by the height of the room.
First, let's find the perimeter of the room.
The formula for finding the perimeter of a rectangle is:
Perimeter = 2 * (length + width)
In this case, the length of the room is 15 feet and the width is 12 feet, so the perimeter is:
Perimeter = 2 * (15 feet + 12 feet)
Perimeter = 2 * 27 feet
Perimeter = 54 feet
Now that we have the perimeter, we can calculate the total area of the walls.
The formula for finding the area of a rectangle is:
Area = Perimeter * Height
The height of the room is 8 feet, so the area of the walls is:
Area = 54 feet * 8 feet
Area = 432 square feet
Therefore, Natasha will be painting 432 square feet in her bedroom.
