Question

the carpet of a room 6.6m by 5.6m costs Rs 3960 and it was made from a roll 70cm wide. find the cost of the carpet per metre

Answer 1

carpet area = 6.6×5.6 =36.96m^2
and the cost given for 36.96 m^2 = 3960
then, cost of carpet per m^2 = 3960/36.96 =107.14

now ,
the area of 70cm carpet for 1m long
= 0.7×1= 0.7m^2

hence,
the cost of carpet per meter = 0.7×107.14=Rs 75

I hope this will help you.....

Answer 2

Answer:

carpet area = 6.6×5.6 =36.96m^2

and the cost given for 36.96 m^2 = 3960

then, cost of carpet per m^2 = 3960/36.96 =107.14

now ,

the area of 70cm carpet for 1m long

= 0.7×1= 0.7m^2

hence,

the cost of carpet per meter = 0.7×107.14=Rs 75
