Answer 2

Step-by-step explanation:

Given -:

A rectangular room is 5 metre long and 5 metre wide find the cost of fencing atta rate of rupees 75 for metre and find the cost of carpeting a room if it cost rupees 86.75 square metre.

To find -:

The cost of carpeting a room.

Solution -:

• Lenth of the room = 5 metre
• Width of the room = 5 metre

According to the question, firstly we have to find the cost of fencing -:

• Perimeter of the rectangular room

= 2 × ( Length + Breadth )

• Perimeter of the room = 2 × ( 5 + 5)
• Perimeter of the room = 2 × 10
• Perimeter of the room = 20 sq. metre

Now , we can easily find the cost of fencing -:

Therefore , the total cost = 20 × 75 sq. metre

= ₹ 1500 sq. metre

Thus,the cost of fencing is ₹1500.

According to the question, area of the room by using the formula -:

• Area = Length × Breadth
• Area = 5 × 5
• Area = 25 metre

According to the question , cost of carpet -:

• Carpet needed to cover the floor = 25 metre
• Cost of per sq. metre = 86.75
• Cost of carpet = ₹(86.75 × 25 )

= ₹ 2168.75

Thus,the cost of fencing is ₹ 1500 sq. metre and the cost of carpet is ₹ 2168.75.
