Question

A rectangular hall 27 m long and 15 m wide, is to be covered with a carpet of width 60 cm. Find the cost of carpeting at ₹ 12 per metre.

Answer 1

Given:

Length of hall = 27 m

Breadth (width) of hall = 15 m

Width of one carpet strip = 60 cm = 0.6 m

Cost = ₹ 12 per metre

Step-wise calculation:

1. Number of strips required across the 15 m width:

Number = 15 ÷ 0.6

= 25 strips

2. Length of each strip = 27 m.

So, total length of carpet needed:

Total length = 25 × 27

= 675 m

3. Cost of carpeting at ₹ 12 per metre:

Total cost = 675 × 12

= ₹ 8,100

The cost of carpeting the hall is ₹ 8,100.
