Carpet is lead on the floor of 8 m/ 5 m leaving a border 0.5 wide all around it what is the perimeter of the carpet?

Dishani Pillai answered • 2 days ago

Understanding the Problem
To find the perimeter of the carpet, we need to first identify its dimensions and then calculate the perimeter based on those dimensions. The carpet measures 8 m by 5 m, and there is a border of 0.5 m around it.
Dimensions of the Carpet
- The length of the carpet: 8 m
- The width of the carpet: 5 m
Calculating the Dimensions Inclu... moreding the Border
Since there is a border of 0.5 m on all sides, we need to add this border to both the length and the width of the carpet.
- Length with border:
- 8 m + 0.5 m + 0.5 m = 9 m
- Width with border:
- 5 m + 0.5 m + 0.5 m = 6 m
Calculating the Perimeter
The formula for the perimeter (P) of a rectangle is given by:
P = 2 × (Length + Width)
Now, plug in the dimensions including the border:
- P = 2 × (9 m + 6 m)
- P = 2 × 15 m
- P = 30 m
Final Answer
The perimeter of the carpet, including the border, is 30 meters.
This calculation helps ensure that you understand both the dimensions of the carpet and how to calculate the perimeter effectively.

Keystone Instructors answered

India is located east of the Prime Meridian (Greenwich) at 82°30'E. The Earth rotates 360° in about 24 hours, meaning it rotates 15° per hour. Therefore, India, being approximately 82.5° east of Greenwich, is ahead by about 5 hours and 30 minutes (82.5° / 15° per hour). This time difference explains why it is 5.30 p.m. in India when it is 12 noon in London. Interestingly, different countries adopt... more
