Solution

## The correct option is C 72 Given a square room of side = 6 m. Area of each tile = 0.5 m2 We know that, area of a square = Side × Side ∴ Area of a square room = 6 × 6 = 36 m2. So, number of tiles required = Area of roomArea of a single tile = 360.5 = 72 Hence, Karan should buy 72 tiles to cover the floor of his room.
