Question

the rate for a 1.20 m wide carpet is rs 40 per metre find the cost of covering a hall 45 m long and 32 m widewith the carpet. also find the cost of carpeting the same hall if the carpet 80 cm wide is at rs 25 per metre

Answer 1

Solution:

Length of floor, L = 45 m

Breadth of floor, B = 32 m

Area of floor = L * B = 45 × 32 = 1440 m²

Width of carpet = 1.2 m

Length of the carpet = 1440/1.2 = 1200 m

Cost for covering a hall with carpet at Rs. 40 per metre = Rs. (40 × 1200) = Rs. 48000

Now, width of carpet, w = 80 cm = 0.8 m

Length of carpet = 1440/0.8 = 1800 m

Cost for covering a hall with carpet at Rs. 25 per metre = Rs. (25 × 1800) = Rs. 45000

Answer 2

Answer:

Step-by-step explanation:

length of floor = 45 m

breadth of floor = 32 m

area of floor = length × breadth = 45 × 32 = 1440 m²

 width of carpet = 1.2 m

 length of the carpet = 1440/1.2 = 1200 m

Total cost = Rs (40 × 1200) = Rs 48000

 width of carpet = 80 cm = 0.8 m

Length of carpet = 14400.8 = 1800

Total cost = 25 × 1800 = Rs 45000
