The cost of painting the walls of a room at ₹75 per m^2 amounts to ₹11.250 and the
cost of carpeting the room at ₹24 per m^2 comes to ₹1878. If the length of the room
is 8.5 m, find the dimensions of the room.
Answers
Answer:
The dimensions of the room is 8.5m × 4.41 m - 9.21
Step-by-step explanation:
Given that the length of the room = 8.5m Let the height of the room be 'h' and the width be 'w'.
Given that the cost of painting the walls of a
room = Rs. 11250
Rate of painting the walls = Rs. 75/m²
Area to be covered in painting the walls = 8.5 × h x 4 (as there are 4 walls)
We know, that Cost = Rate × Area
=>
11250 = 75 × (8.5 × h × 4) X
=>
h = 4.41 m
The height of the room is 4.41 m.
Given that the cost of carpeting the room = Rs. 1878
Rate of carpeting = Rs. 24/m²
Area to be covered in carpeting = 8.5 x |
We know, that Cost = Rate * Area
1878 = 24 x (8.5 × 1)
| = 9.21 m
The length of the room is 9.21 m.
Answer:

The height of the room is 4.41 m.
Given that the cost of carpeting the room = Rs. 1878
Rate of carpeting = Rs. 24/m²
Area to be covered in carpeting = 8.5 x |
We know, that Cost = Rate * Area
1878 = 24 x (8.5 × 1)
| = 9.21 m
The length of the room is 9.21 m.
