Rectangle: A = length × width

Square: A = side²

Circle: A = πr²

Triangle: A = ½ × base × height

Parallelogram: A = base × height

Trapezoid: A = ½(b₁ + b₂) × height

Ellipse: A = πab

Rhombus: A = ½ × d₁ × d₂

1 m² = 10.764 ft²

1 ft² = 144 in²

1 acre = 43,560 ft²

Area measures the amount of space inside a 2D shape. It's expressed in square units like cm², m², ft², etc.

Regular shapes have standard formulas, while irregular shapes may need to be broken down into simpler shapes or use integration methods.

Always ensure your measurements use the same units. The result will be in square units (length units squared).

Area calculations are used in construction, landscaping, painting, flooring, farming, and many other real-world applications.
