Area Formulas
| Shape | Formula | Variables |
|---|---|---|
| Rectangle | Length × Width | l = length, w = width |
| Triangle | (Base × Height)/2 | b = base, h = height |
| Circle | π × Radius² | r = radius |
| Square | Side² | s = side |
Calculation Process
The concept of area measurement dates back to ancient civilizations. Modern formulas derive from geometric principles developed by Greek mathematicians. For regular shapes, area is calculated using standardized formulas, while irregular shapes use integration in calculus or approximation methods.

Frequently Asked Questions
How to calculate area of irregular shapes?
For irregular shapes, divide them into regular shapes, calculate each area separately, and sum them up. Advanced methods like integration or digital tools (CAD software) provide more accurate results for complex forms.
What units are used in area calculation?
Common units include square meters (m²), square feet (ft²), and acres. Always maintain consistent units throughout calculations and convert when necessary using conversion factors (1 m² = 10.764 ft²).
