प्रश्न
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:
100 cm and 144 cm
उत्तर
Area of rectangle = 100 × 144
= 14400 cm
Area of one tile = 5 × 12
= 60 cm2
Number of tiles = `"(Area of rectangle)"/"(Area of one tile)"`
= `14400/60`
= 240
Hence, 240 tiles are needed.
