Karan wants to cover the floor of his room with lavish tiles. The floor of his room is in the shape of a square with sides measuring 6 m. The shopkeeper told him that the area of each tile is 0.5 m2. How many tiles should Karan buy?
72
Area of the room = Side × Side
= 6 × = 36 m2.
Area of each tile = 0.5 m2
So, number of tiles required = Area of roomArea os a single tile
= 360.5 = 72.
