Question

9. Find the cost of carpeting a room 15 m long
and 12 m wide at the rate of 175 per square
metre.​

Answer 1

Answer:

Because,

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)

Answer 2

Answer:

31500

Step-by-step explanation:

area of room = 15*12=180

cost of money = area and rate of cost=180*175=31500
