1) the cost of papering its walls at the rate of rupees 25 per m^2

2)the cost of carpeting its lower at the rate of rupees 154 per m^2

please give the answer with method.......

Answer 1

1) The walls are of 2 types -
Breadth Wall = B×H = 30 × 16 = 480m²
Length Wall = L×H = 45 × 16 = 720m²

Now, each wall is 2 in number. So,
480m²+720m²×2 = 2400m²

Then, if each m² covering of wall costs ₹25,
2400×25 = ₹60000

Answer :- ₹60000

2) The question says that the hall is 45m long
and 30m broad.

So,
Area = 30m×45m = 1350m²

Now, if each m²'s carpeting requires ₹154,
Then,
1350×154 = ₹207900

Answer :- ₹207900
