Lizzie and her husband need to paint the walls of their bedroom. The room is 12 feet by 14 feet, and it has a ceiling that is 10 feet high. What is the area that they need to paint?
To calculate the area that they need to paint, we need to determine the area of the walls.
Since there are 4 walls in a room, we need to find the area of each wall and then add them all together.
The first wall is 12 feet by 10 feet, so its area is 12 feet * 10 feet = 120 square feet.
The second wall is 12 feet by 10 feet, so its area is also 120 square feet.
The third wall is 14 feet by 10 feet, so its area is 14 feet * 10 feet = 140 square feet.
The fourth wall is 14 feet by 10 feet, so its area is also 140 square feet.
Therefore, the total area that they need to paint is 120 + 120 + 140 + 140 = 520 square feet.
