Most Upvoted Answer
The length and breadth of a photograph is 2.5 cm and 12cm respectively...
Understanding the Problem
To determine the length of wooden frame needed to frame a photograph, we first need to calculate the perimeter of the photograph. The dimensions given are:
- Length = 12 cm
- Breadth = 2.5 cm
Calculating the Perimeter
The perimeter (P) of a rectangle can be calculated using the formula:
- P = 2 * (Length + Breadth)
Now, substituting the values:
- Length = 12 cm
- Breadth = 2.5 cm
Step-by-Step Calculation
- Calculate the sum of length and breadth:
- Length + Breadth = 12 cm + 2.5 cm = 14.5 cm
- Multiply by 2 to find the perimeter:
- P = 2 * 14.5 cm = 29 cm
Conclusion
The total length of wooden frame needed to frame the photograph is:
- 29 cm
The wooden frame will need to be cut to this total length to adequately surround the photograph, providing both support and an aesthetic finish.
Summary
- Dimensions of Photograph:
- Length: 12 cm
- Breadth: 2.5 cm
- Perimeter Calculation:
- P = 2 * (Length + Breadth) = 29 cm
This concise breakdown allows for a clear understanding of the calculations required for framing the photograph.
