Area of bathroom is 6 metres calculation on how many tiles needed to tile bathroom if each tile have these dimensions 550 millimetres ×550 millimetres ?

First, convert the area of the bathroom from square meters to square millimeters:
6 square meters = 6,000,000 square millimeters

Next, calculate the area of each tile in square millimeters:
550 mm x 550 mm = 302,500 square millimeters

Finally, divide the total area of the bathroom by the area of each tile to determine how many tiles are needed:
6,000,000 square millimeters / 302,500 square millimeters per tile = 19.83 tiles

Since you cannot have a fraction of a tile, you would need to round up to the nearest whole number. Therefore, you would need 20 tiles to tile the bathroom.

Step 1: Convert area to square meters

Area = 6 square meters

Step 2: Convert tile dimensions to meters

Tile length = 550 mm = 0.55 meters
Tile width = 550 mm = 0.55 meters

Step 3: Calculate area of one tile

Area of one tile = Length x Width = 0.55 m x 0.55 m = 0.3025 square meters

Step 4: Calculate the number of tiles needed

Number of tiles = Bathroom area / Area of one tile
= 6 square meters / 0.3025 square meters per tile
= 19.86 tiles

Conclusion:

Approximately 20 tiles are needed to tile the bathroom.
