1. What is Rectangle Measurement?

Rectangle measurement involves calculating the perimeter (total distance around the rectangle) and area (space enclosed within the rectangle) based on its length and width.

2. How Does the Calculator Work?

The calculator uses these fundamental formulas:

Where:

• \( P \) — Perimeter (units)
• \( A \) — Area (square units)
• \( l \) — Length of the rectangle (units)
• \( w \) — Width of the rectangle (units)

Explanation: The perimeter is calculated by adding all sides, while the area is calculated by multiplying length by width.

3. Importance of Rectangle Calculations

Details: These calculations are essential in construction, architecture, land measurement, and various engineering applications where rectangular shapes are common.

4. Using the Calculator

Tips: Enter length and width in the same units. The calculator will provide perimeter in linear units and area in square units. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between perimeter and area?
A: Perimeter measures the total distance around the rectangle (a length), while area measures the space inside (a surface).

Q2: Do the units matter?
A: Yes, both dimensions must be in the same units. The perimeter will be in those units, and area in square units.

Q3: Can I use this for squares?
A: Yes, a square is a special rectangle where length equals width.

Q4: What if I only know the area and one side?
A: You can calculate the missing dimension: width = area/length or length = area/width.

Q5: How precise are the calculations?
A: The calculator provides results rounded to 2 decimal places for clarity.
