How many 10cm x 10cm tiles are needed to tile an area 2m long and 1.2m wide?

one tile area = .1*.1 = .01 m^2

total area = 2.4 m^2

2.4 /.01 = 240/1 = 240 tiles

Thanks so much

You are welcome :)

To find out how many 10cm x 10cm tiles are needed to tile the given area, we need to follow these steps:

Step 1: Convert the dimensions of the area into the same units.
The given dimensions are 2m (length) and 1.2m (width). Since the dimensions of the tiles are given in centimeters (cm), we need to convert the dimensions of the area to centimeters as well.

1 meter = 100 centimeters
Therefore, the length of the area is 2m x 100cm/m = 200cm, and the width is 1.2m x 100cm/m = 120cm.

Step 2: Calculate the area of the tiles.
The area of each tile is given as 10cm x 10cm = 100 square cm.

Step 3: Calculate the total area of the given area.
To find the total area of the given area, multiply the length by the width:
Total area = Length x Width = 200cm x 120cm = 24,000 square cm.

Step 4: Determine the number of tiles needed.
Divide the total area of the given area by the area of each tile to obtain the number of tiles needed:
Number of tiles = Total area / Area of each tile = 24,000 square cm / 100 square cm = 240 tiles.

So, to tile an area that is 2m long and 1.2m wide, you would need 240 tiles measuring 10cm x 10cm each.
