What is the length (in cm) of string needed to mark the boundary of a ...
Understanding the Problem
To find the length of the string needed to mark the boundary of a rectangle, we need to calculate the perimeter of the rectangle. The perimeter is the total distance around the rectangle.
Formula for Perimeter
The formula to calculate the perimeter (P) of a rectangle is:
P = 2 × (Length + Width)
Where:
- Length = 83 cm
- Width = 54 cm
Calculating the Perimeter
Let's substitute the values into the formula:
- First, add the length and width:
- Length + Width = 83 cm + 54 cm = 137 cm
- Next, multiply the sum by 2:
- P = 2 × 137 cm = 274 cm
Conclusion
Thus, the length of string needed to mark the boundary of the rectangle is 274 cm.
Options Review
- a) 264 cm
- b) 274 cm (Correct Answer)
- c) 284 cm
- d) 294 cm
From our calculation, option 'B' is the correct answer.
Key Takeaway
To find the perimeter of a rectangle, always remember to use the formula P = 2 × (Length + Width). This will help you solve similar problems in the future effectively!
