Given :
A rectangular hall 12 m long and 6m broad. Its floaring is to be made of square tiles of side 30 cm.
To find :
How many tiles will fit. in the entire hall ? How many tiles would be required if tiles of 15 cm were used?
Solution :
Length = 12 m
= 12 × 100 = 1200 cm
Breadth = 6m
= 6 × 100 = 600 cm
Area of the Room = L × B
= 1200 × 600
= 720000 cm
Area of Square Tile = a × a
= 30 × 30
= 900 cm
Tiles required = Area of room/ Area of tiles.
= 720000/ 900
= 800 tiles Required.
In case of 15 tiles
a = 15 cm
Area of Tile = 15 × 15
= 225
Required Tiles = Area of room/ Area of tiles
= 720000/225
= 3200 tiles Required.
