What is the formula for area?

Answer 1

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

Answer 2

Depends on the shape. There are different formulae for different shapes: triangles, quadrilaterals, regular polygons, circles, ellipses.

Answer 3

area formulas are for working out the area of a shape
