Tiles are to be fixed on the floor of a verandah which is 9 m long and 6m wide. How many square tiles of side 15 cm are required to cover the floor of the verandah ?​

Answer 1

Given:

Tiles are to be fixed on the floor of a verandah which is 9 m long and 6 m wide.

To find:

How many square tiles of side 15 cm are required to cover the floor of the verandah ?​

Solution:

From the given information, we have the data as follows.

Tiles are to be fixed on the floor of a verandah which is 9 m long and 6 m wide.

The area of the floor is computed as follows.

Af = Area of rectangle.

Af = 9 × 6

Af = 54 m²

The area of the tile is computed as follows.

At = Area of the square

At = 15²

At = 225 cm²

At = 0.0225 m²

Thus, the number of tiles required to cover the verandah is,

N = Af / At

N = 54 / 0.0225

N = 2400

Therefore, 2400 square tiles of side 15 cm are required to cover the floor of the verandah.

Answer 2

Answer:

36000 tiles fixed in floor
