Lizzie and her wife 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?(1 point)
ft.2
To find the area that they need to paint, we need to calculate the surface area of the four walls in the bedroom.
First, let's find the area of the walls on the longer sides of the room. Since the room is 12 feet by 14 feet, the longer walls will have a height of 10 feet and a width of 12 feet. The area of each of these walls is 10 feet * 12 feet = <<10*12=120>>120 square feet.
Next, let's find the area of the walls on the shorter sides of the room. These walls will have a height of 10 feet and a width of 14 feet. The area of each of these walls is 10 feet * 14 feet = <<10*14=140>>140 square feet.
Since there are two shorter walls and two longer walls in the room, we need to multiply the area of each type of wall by the number of that type of wall.
So the area of the two longer walls is 120 square feet * 2 = <<120*2=240>>240 square feet.
And the area of the two shorter walls is 140 square feet * 2 = <<140*2=280>>280 square feet.
Finally, to find the total area they need to paint, we add the areas of all four walls together:
240 square feet + 280 square feet = <<240+280=520>>520 square feet.
So, Lizzie and her wife need to paint 520 square feet.
