Area Formulas by Shape
- Square: A = side²
- Rectangle: A = length × width
- Triangle: A = (1/2) × base × height
- Circle: A = πr²
- Trapezoid: A = (1/2) × (base a + base b) × height
Area measures how much two-dimensional space a shape covers, expressed in square units (like m² or ft²). The formula needed depends entirely on the shape, which is why this tool switches its inputs based on the shape you pick.
