Question

A floor is 40 m Long and 15m broad. It is covered with tiles each measuring 60cm by 50cm. Find the number of tiles required to cover the floor

Answer 1

Length of floor = 40 m
Breadth of floor = 15 m
Area of the floor = length x breadth
                          = 40 m x 15 m
                          =600 m^2

Length of the tiles = 60 cm = 0.6 m
Breadth of the tiles = 50 cm = 0.5 m
Area of the tiles      =length x breadth
                               =0.6 m x 0.5 m
                               =0.3 m^2

Tiles required = Area of room / area of tiles
                       =600 / 0.3 
                       =2000 tiles

So 2000 tiles are required to cover the floor
