Length of floor = 4.5 m and width of floor = 3.6 m
Area of floor = length × Breadth =4.5×3.6m2 [∵width=breadth=3.6m]
Side of square tile =6cm=6100=0.06m
Area f one tile =(side)2=0.06×0.06m2
NUmber of tiles Area of floorArea of one tile=4.5×3.60.06×0.06=4500
∵ cost fo 1 tile = ₹ 23.25
∴ cost of 4500 tiles ₹23.25×4500=₹104625
Hence,₹ 104625 are required to cover the floor with tiles .
