Q. |
How many tiles whose length and breadth are 12 cm and 5 cm respectively will be needed to fit in a rectangular region whose length and breadth are respectively 144 cm and 100 cm: |

✖ A. |
160 |

✔ B. |
240 |

✖ C. |
320 |

✖ D. |
450 |

**Solution:**

Option(**B**) is correct

Total area of the region

\(=100\times 144\)

\(=14400\text{ cm}^2\)

Area of one tile

\(=12\times 5\)

\(=60\text{ cm}^2\)

Number of tiles required

\(=\dfrac{14400}{60}\)

\(=240\)

Therefore, 240 tiles are required.

**Edit:** Thank you **Pawan Sharma**, added rectangular region's length and width in order to complete the question.
