- 348644
- 344864
- 384644
- None of these
Correct Option: B
We require the least number of square tiles, hence each tile must be of maximum dimensions.
Hence, the maximum dimensions of a tile = HCF of 16.58 m and 8.32 m
Now, 16.58 m = 16.58 × 100 cm = 1658 cm
8.32 m = 8.32 × 100 cm = 832 cm
Hence, the side of a square tile = 2 cm
| ∴ Required number of tiles = | Area of a square tile |
| Required number of tiles = | = 344864 | 2 × 2 |
