Answer 1

Answer:

91800

Step-by-step explanation:

area of floor - side*side- 900*900

--810000m2

area of tile--side into side -- 3*3--9m2tiles

needed to cover the floor -- 810000/9--90000

cost of one tile--12

cost of 90000 tiles -- 90000*12--918000

Answer 2

Answer:

No. of tiles = 90000

Cost of all tiles = Rs. 1080000

Step-by-step explanation:

Area of floor = 900 x 900

= 810000 m Sq.

Area of 1 tile = 3 x 3

= 9 m Sq.

No. of tiles needed = Area of floor / Area of tiles

= 810000 / 9

= 90000

Cost of all tiles = No. of tiles x Cost of 1 tile

= 90000 x 12

= Rs. 1080000
