The total cost of papering the 4 walls is Rs. 1104

Step-by-step explanation:

The given is:

• The length of a room is 3 times its breadth
• Its height is 4.6 m
• The total cost of carpeting the floor of a room at the rate of Rs. 60 per square meter is Rs. 4500

We need to find the total cost of papering the 4 walls at the rate of Rs. 6

Assume that the breadth of the room is x m

∵ The length of the room is 3 times its breadth

∵ The breadth of the room is x m

∴ The length of the room is 3 x m

∵ The floor of the room is shaped a rectangle

- Area of the rectangle = length × breadth

∴ The area of the floor = (3 x) × (x) = 3 x²

∵ The rate of the carpeting is Rs. 60 per square meter

- Multiply the area of the floor by 60 to find the total cost of carpeting

∴ The total cost of carpeting = 3 x²(60) = 180 x²

∵ The total cost of carpeting the floor is Rs. 4500

- Equate the two sides of total cost to find x

∴ 180 x² = 4500

- Divide both sides by 180

∴ x² = 25

- Take √ for both sides

∴ x = 5

∴ The breadth of the room = 5 m

∵ The length of the room is 3 x

∴ The length of the room = 3(5) = 15 m

The four walls of the room has dimensions length × height , breadth × height , length × height , breadth × height ⇒ (each two opposite walls have same dimensions)

∵ The length = 15 m , breadth = 5 m , height = 4.6 m

∴ The area of the four walls = 2(15 × 4.6) + 2(5 × 4.6)

∴ The area of the four walls = 138 + 46

∴ The area of the four walls = 184 m²

∵ The rate per meter square of papering is Rs. 6

- Multiply the area of the four walls by 6 to find the total cost

  of papering

∴ The total cost of papering = 184 × 6

∴ The total cost of papering = Rs. 1104

The total cost of papering the 4 walls is Rs. 1104

Hey there! Let me help you out!

No, this is not true. The answer to your question is: 351800<605908. This means that 605908 is bigger than 351800. To find this out, count how many digits there are in both the numbers. The number with more digits is bigger than the other number. If both the numbers have the same number of digits, then see the starting number of each number and so forth, if they are the same. For example, for this question, count how many numbers there are in each number. They both have 6 numbers so u can't make out anything from that. Next see the starting number for each of them. In 351800, the starting number is 3. In 605908, the starting number is 6. Since 6 is larger than three, 605908 is bigger than 351,800.

Thank you! Hope it helps!
