Rectangle Area Calculator
Formula Explanation
Area = Length × Width
A rectangle is a quadrilateral with four right angles. The area is calculated by multiplying the length by the width. This formula works because a rectangle can be divided into unit squares, and the total number of squares equals length × width.

Frequently Asked Questions
How accurate are the calculations?
Our calculator provides results accurate to multiple decimal places using standard mathematical formulas. For practical applications, round to appropriate precision for your needs.
Can I calculate irregular shapes?
For irregular shapes, break them into simpler geometric shapes, calculate each area separately, then combine the results. This approach works for most complex polygons.
What units can I use?
You can use any unit of length (inches, feet, meters, etc.), but ensure consistency. The result will be in square units of whatever measurement you input (e.g., square feet if you input feet).
Is this calculator free to use?
Yes, our area calculator is completely free to use with no limitations. No registration or download required. Access it anytime from any device with internet connection.
How do I calculate area for construction projects?
For construction, measure rooms as rectangles, calculate each area, and sum them up. Add 5-10% for cutting waste. For flooring or tiling, account for pattern matching and irregular cuts near walls.
