What is Area?
Area is the measure of the space inside a two-dimensional shape. It's calculated in square units such as square centimeters (cm²), square meters (m²), square inches (in²), or square feet (ft²).
Area Formulas:
- Rectangle: A = length × width
- Square: A = side²
- Triangle: A = ½ × base × height
- Circle: A = π × radius²
- Parallelogram: A = base × height
- Trapezoid: A = ½ × (base₁ + base₂) × height
Applications of Area:
- Flooring and carpet calculations
- Painting and wallpaper estimation
- Land and property measurements
- Garden and landscaping planning
- Construction and architecture
- Material quantity calculations
