How many tiles whose length and breadth are 12cm and 5cm respectively ...
(a) Area of region = 100 cm x 144 cm = 14400 cm.sq
Area of one tile = 5 cm x 12 cm = 60 cm.sq
Number of tiles = \frac{Area\ of\ region}{Area\ of\ one\ tile}Area of one tileArea of region = 240
Thus, 240 tiles are required.

Calculating the Number of Tiles Needed
Rectangular Region 1: Length = 100 cm, Breadth = 144 cm
- Area of one tile = 12 cm x 5 cm = 60 cm²
- Area of the rectangular region = 100 cm x 144 cm = 14400 cm²
- Number of tiles needed = Area of rectangular region / Area of one tile
- Number of tiles needed = 14400 cm² / 60 cm² = 240 tiles
Therefore, 240 tiles of dimensions 12 cm x 5 cm will be needed to fit in a rectangular region with length 100 cm and breadth 144 cm.
Rectangular Region 2: Length = 70 cm, Breadth = 36 cm
- Area of the rectangular region = 70 cm x 36 cm = 2520 cm²
- Number of tiles needed = Area of rectangular region / Area of one tile
- Number of tiles needed = 2520 cm² / 60 cm² = 42 tiles
Therefore, 42 tiles of dimensions 12 cm x 5 cm will be needed to fit in a rectangular region with length 70 cm and breadth 36 cm.
