How many tiles of length and breadth 12 cm and 5 cm respectively will be needed to cover a rectangular region whose length and breadth are 100 cm and 144 cm respectively?

Given:

Length of the tile $=12\ cm$

Breadth of the tile $=5\ cm$

Length of the rectangular region $=100\ cm$
Breadth of the rectangular region $=144\ cm$
 To do:

We need to find the number of tiles needed to cover the rectangular region.

Solution:

Area of a tile $=12\times5\ cm^2=60\ cm^2$

Area of the rectangular region $=100\times144\ cm^2=14400\ cm^2$

The number of tiles required to cover the rectangular region $=$ Area of the rectangular region $\div$ Area of a tile

$=\frac{14400}{60}$

$=240$

Therefore, 240 tiles are needed to cover the rectangular region.
