Ragini wants to lay tiles of size 20 cm x 20 cm on the floor of her kitchen
which is 8 m in length and 4 m in breadth. How many tiles are required to
completely cover the floor? (Hint: Divide the area of the kitchen by the area
of the tiles.)

Answer:

To find out how many tiles Ragini needs, we first need to calculate the area of her kitchen and the area of each tile. The area of the kitchen is 8 m x 4 m = 32 square meters. The area of each tile is 20 cm x 20 cm = 0.2 m x 0.2 m = 0.04 square meters. Now, we divide the area of the kitchen by the area of each tile:

32 square meters (kitchen area) / 0.04 square meters (tile area) = 800 tiles.

So, Ragini needs 800 tiles to completely cover the floor.

Answer:

800 tiles

Step-by-step explanation:

When calculating the number of tiles needed to cover a floor, we need to make sure that the width of the tiles evenly divides into the length and breadth of the area, else rounding up may be necessary. This is a practical consideration to ensure we have enough tiles to cover the entire floor without leaving any gaps.

So, to calculate the number of tiles needed to completely cover the kitchen floor, which is 8 m in length and 4 m in breadth, we should first determine if the width of the tiles evenly divides into the length and breadth of the area.

Convert the given dimensions from meters to centimeters by multiplying them by 100:

Length:  8 m = 8 × 100 = 800 cm

Breadth:  4 m = 4 × 100 = 400 cm

Now, divide each measurement by the width of one tile (20 cm):

Length:  800 cm ÷ 20 cm = 40

Breadth:  800 cm ÷ 20 cm = 20

Since the tiles divide evenly into the length and breadth, we can calculate how many tiles are needed to completely cover the floor by dividing the area of the floor by the area of one tile.

Area of the floor = 800 × 400 = 320,000 cm²

Area of one tile = 20 × 20 = 400 cm²

Number of tiles = 320,000 cm² ÷ 400 cm² = 800

Therefore, the number of tiles required to completely cover the floor is 800.

Additional Notes

After calculating how many tiles fit along the length and breadth of the kitchen floor, we could determine the total number of tiles required by simply multiplying these numbers: 40 × 20 = 800.
