1. What is Percentage Change in Length of Rectangle?

Percentage Change in Length of Rectangle is the increase or decrease in the length of the rectangle compared to its original length, expressed as a percentage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L\%Change \) — Percentage Change in Length of Rectangle
• \( B\%Change \) — Percentage Change in Breadth of Rectangle

Explanation: This formula calculates the percentage change in length required to maintain the same area when the breadth changes by a certain percentage.

3. Importance of Percentage Change Calculation

Details: Calculating percentage changes in dimensions is crucial for maintaining proportional relationships in geometric shapes, particularly when area preservation is required during dimensional modifications.

4. Using the Calculator

Tips: Enter the percentage change in breadth of the rectangle. The calculator will compute the corresponding percentage change in length needed to maintain the original area.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage change in length indicate?
A: A negative percentage change indicates a decrease in length, while a positive percentage change indicates an increase.

Q2: How does this relate to area preservation?
A: This calculation helps determine how much the length must change to maintain the same area when the breadth changes.

Q3: Can this formula be used for other shapes?
A: This specific formula applies to rectangles. Other shapes may have different relationships between dimensional changes and area preservation.

Q4: What if both length and breadth change simultaneously?
A: The formula calculates the required length change for a given breadth change to maintain area. For simultaneous changes, a different approach would be needed.

Q5: Are there limitations to this calculation?
A: This calculation assumes area preservation and applies specifically to rectangular shapes with the given percentage change in breadth.
