Complete Guide: Area of Rectangle Formula & Applications
What is Rectangle Area?
The area of a rectangle is the space enclosed within its four sides, measured in square units. Rectangles are everywhere around us - from mobile screens and books to rooms and fields.
"Clear diagram showing rectangle with length 'l' and width 'w'. Formula A = l × w displayed prominently. Light shading inside rectangle represents area."
Understanding rectangle area is fundamental in geometry and essential for practical applications in construction, design, and daily life.
Rectangle Area Formula
A = l × w
Where:
- l = Length of the rectangle (longer side)
- w = Width of the rectangle (shorter side)
- A = Area in square units (cm², m², ft², etc.)
Why This Formula Works?
The formula comes from dividing the rectangle into unit squares. If length is 'l' units and width is 'w' units, we have 'l' columns and 'w' rows of unit squares, totaling l × w squares.
Solved Examples
Example 1: Basic Calculation
Problem: Find area of rectangle with length 10 cm and width 6 cm.
Answer: Area = 60 square centimeters
Example 2: Real Application
Problem: A room measures 15 ft by 12 ft. How much carpet is needed?
Answer: 180 square feet of carpet required

Tips for Mastering Rectangle Area
Area Conversion Table
| From | To | Multiply by | Example |
|---|---|---|---|
| cm² | m² | 0.0001 | 10000 cm² = 1 m² |
| ft² | m² | 0.0929 | 10.76 ft² ≈ 1 m² |
| in² | cm² | 6.4516 | 1 in² ≈ 6.45 cm² |
| yd² | m² | 0.8361 | 1 yd² ≈ 0.84 m² |
| km² | m² | 1000000 | 1 km² = 1,000,000 m² |
