a class wanted to cover part of their wall with beatiful tiles, the tiles are square ,one foot on each side ,if the wall to be covered is in the shape of a 10 foot by 12 foot rectangle ,how many tiles will be needed to cover the wall ?
A = LW
A = 10 * 12
A = 120 square feet (120 tiles)
To find the number of tiles needed to cover the wall, we need to calculate the area of the wall and then divide it by the area of each tile.
Step 1: Calculate the area of the wall
The wall is in the shape of a rectangle with dimensions 10 feet by 12 feet. The area of a rectangle is calculated by multiplying its length by its width. Therefore, the area of the wall can be found as follows:
Area of the wall = Length × Width
Area of the wall = 10 feet × 12 feet = 120 square feet
Step 2: Calculate the area of each tile
The tiles are square, with each side measuring 1 foot. The area of a square is calculated by multiplying the length of one side by itself. Therefore, the area of each tile can be found as follows:
Area of each tile = Side length × Side length
Area of each tile = 1 foot × 1 foot = 1 square foot
Step 3: Calculate the number of tiles needed
To calculate the number of tiles needed to cover the wall, we need to divide the area of the wall by the area of each tile. This will give us the total number of tiles required.
Number of tiles = Area of the wall ÷ Area of each tile
Number of tiles = 120 square feet ÷ 1 square foot = 120 tiles
Therefore, the class will need 120 tiles to cover the wall.
