Answer:
2400 square tiles of side 15 cm are required
Step-by-step explanation:
8 Ans-
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.
Hope it helps..
