Question

The cost of carpeting a hall 12 m wide with a carpet of width 90cm at Rs 150 per metre is Rs 30000. find the length of the hall.​

Answer 1

Similar answer:-

From the question,

Total cost of carpenting =Rs.6000

Rate of carpenting =Rs.50 per meter

Then,

Length of the carpet =(6000/50)=120m

∴ Area of the carpet =(120×(75/100))=90m

2

Area of the floor = Area of the carpet =90m

2

Hence, the width of the room = (Area / length)

=(90/15)

=6m.

hope it helps ♡
