Answer 2

Calculating the Number of Tiles Needed to Cover the Floor

To calculate the number of tiles needed to cover the floor, we can start by finding the total area of the floor and then divide it by the area of each tile to determine the number of tiles required.

The total area of the floor can be calculated using the formula: Total Area = Length × Width

Given: - Length of the room = 18 m - Width of the room = 4 m - Area of each tile = 3 m²

Using the given values: Total Area = 18 m × 4 m

Now, let's calculate the total area of the floor.

Calculation

Total Area = 18 m × 4 m = 72 m²

Now, to find the number of tiles needed, we can divide the total area of the floor by the area of each tile: Number of Tiles = Total Area / Area of Each Tile

Calculation

Number of Tiles = 72 m² / 3 m² = 24 tiles

So, 24 tiles are needed to cover the floor.
