Answer 1

$\huge\underline\mathrm\pink{Answer}$

Dimnesions of the room is 5.6m x 3.6m

= 5600cm x 3600 cm

Area of the room = 5600 x 3600 cm²

= 2,01,60,000 cm²

Length of each side of the square tile = 10 cm

Area of tile = 10 x 10 cm² = 100 cm²

No. of tiles to be laid = 2,01,60,000/100

= 201600

Cost of one tile = Rs. 2.50

Total cost = 201600x 2.50

= Rs.504000

Answer 2

Dimensions of the room is 5.6m×3.6m

=5600cm×3600cm

area of the room=5600×3600cm^2

=20160000cm^2

length of each side of the square tile=10cm

area of tile=10×10cm=100cm^2

no. of tiles to be laid =20160000/100

=201600

cost of one tile =2.50

total cost=2.50×201600

=504000
