Answer 1

Answer:

area of the hall= area of the carpet= 20×18=360m^2

length of the carpet=360÷1.5=240m

1m^2 costs Rs10

360m^2 costs 10×360=Rs3600

Answer 2

Answer:

Rs 3600

Step-by-step explanation:

Area of the hall = Area of the carpet

20 × 18 = 360m^2

Length of the carpet = 360 ÷ 1.5 = 240m

1m^2 cost = rs 10

360m^2 costs 10× 360 = Rs3600

Hence, cost of carpet = Rs 3600
