The computation of the area of a two - dimensional shape varies with the shape.

The common formulas include :

  • Parallelogram, Rectangle or square: Length x width
  • Triangle: 1/2 (height x width)
  • Trapezoid : 1/2 (max width + min width) x height
  • Circle : pi x radius2

* Regular Oval : can be estimated as 0.8 (length x width)

Length x width = area
