the answer of this question is
length of the floor = 7.2m = 720cm
breadth of the floor = 5.8m = 580cm
area of the floor = 720cm × 580cm
area of the tile = 20cm × 20cm
No. of tiles = area of floor/area of tiles
No. of tiles =(720 cm × 580cm)/(20cm ×20 cm)
no. of tiles = 1044
no. of tiles in dozen = 1044/12 = 87 dozen
cost of 87 dozen at the rate of Rs 276/dozen = Rs 276 × 87 = Rs 24012
length of the floor = 7.2m = 720cm
breadth of the floor = 5.8m = 580cm
area of the floor = 720cm × 580cm
area of the tile = 20cm × 20cm
No. of tiles = area of floor/area of tiles
No. of tiles =(720 cm × 580cm)/(20cm ×20 cm)
no. of tiles = 1044
no. of tiles in dozen = 1044/12 = 87 dozen
