Erika is painting her living room. The room measures 10.5 feet by 11.5 feet. The ceiling is 10 feet high. What is the wall area of the room?
I got 440 st ft
Right.
2(10.5 * 10) + 2(11.5 * 10) = ?
Thanks!!
I posted another question maybe you can help me out
If Grace's $98,760 home appreciates three percent a year, will she have enough appreciation to try to sell the home for a $15,000 profit in five years?
value after 5 years
= 98760(1.03)^5 = 114489.91
What do you think?
To find the wall area of the room, we need to calculate the total area of all four walls.
First, let's calculate the area of the two longer walls. Since the height of the ceiling is 10 feet, the area of each longer wall would be:
10 feet (height) x 10.5 feet (length) = 105 square feet
So, the total area of the two longer walls is 105 square feet x 2 = 210 square feet.
Next, let's calculate the area of the two shorter walls. Since the height of the ceiling is 10 feet, the area of each shorter wall would be:
10 feet (height) x 11.5 feet (length) = 115 square feet
Therefore, the total area of the two shorter walls is 115 square feet x 2 = 230 square feet.
To find the wall area of the room, we add the areas of the two longer walls and the two shorter walls:
210 square feet + 230 square feet = 440 square feet
So, the wall area of the room is 440 square feet.
