Best answer

Length of the floor = 4.5 m

= (4.5 × 100) cm = 450 cm

Width of the floor – 3.6 m – (3.6 × 100) cm = 360 cm

∴ Area of the floor – (450 × 360) cm2 = 162000 cm

Side of a square tile = 6 cm

∴ Area of one square tile = (6 × 6) cm2 = 36 cm2

Number of tiles required to cover the floor

= Area of floor/ Area of one tile

= 4500

Now, cost of one tile = ₹ 23.25

∴ Cost of 4500 tiles =₹ (23.25 × 4500)

= ₹ 104625
