​

Answer 1

Answer:

Answer:

2400 tiles

Rs 10800

Step-by-step explanation:

Area of floor = length * width

Area of floor = 9 * 6 = 54 m^2

Area of a tile = 15 cm * 15cm

= (15/100) m * (15/100) m

= 225/10000 m^2

Number of tile required to cover floor = floor area / tile area

Number of tile required to cover floor = 54 / (225/10000)

= 540000/225

= 2400 tiles

Cost of one tile = Rs 4.5

cost of 2400 Tiles = 2400 * 4.5 = Rs 10800

Answer 2

2400 tiles

Rs 10800

Step-by-step explanation:

Area of floor = length * width

Area of floor = 9 * 6 = 54 m^2

Area of a tile = 15 cm * 15cm

= (15/100) m * (15/100) m

= 225/10000 m^2

Number of tile required to cover floor = floor area / tile area

Number of tile required to cover floor = 54 / (225/10000)

= 540000/225

= 2400 tiles

Cost of one tile = Rs 4.5

cost of 2400 Tiles = 2400 * 4.5 = Rs 10800
