📐 Area Calculator
Calculate the area of rectangles, circles, triangles, and trapezoids.
Area Formulas for Common Shapes
Rectangle: length × width. Circle: π × radius². Triangle: ½ × base × height. Trapezoid: ½ × (base₁ + base₂) × height. These formulas are fundamental in geometry, construction, landscaping, and many practical applications.
Converting Area Units
Area is measured in square units. To convert between units, square the linear conversion factor. For example, 1 square meter = 10.764 square feet, and 1 acre = 43,560 square feet.
