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:
(a) 100 cm and 144 cm (b) 70 cm and 36 cm
(a) Length of the rectangular region = 100 cm
Breadth of the rectangular region = 144 cm
Area of the rectangular region = length
breadth
sq cm
Length of 1 tile = 12 cm
Breadth of 1 tile = 5 cm
Area of 1 tile = length
breadth = (12
5) sq cm
Number of tiles = (Area of the rectangular region)/(Area of 1 tile)
(b) Length of the rectangular region = 70 cm
Breadth of the rectangular region = 36 cm
Area of the rectangular region = length
breadth
sq cm
Area of 1 tile = length
breadth = (12
5) sq cm
Number of tiles = (Area of the rectangular region)/(Area of 1 tile)
