Area refers to the amount of space that a two-dimensional figure occupies. Its standard unit is square units represented as square feet or square inches. Calculating it requires the measurement of the length and the width.

For Rectangle, multiply the length (l) and breadth (b). For Triangle: Multiply the width and the height and divide the whole of it by 2. For Trapezoid: Multiply the sum of the parallel sides with its height and divide the whole by 2. For a Circle: πr2, the value of the pie is approximately 3.14. For Sector: (θ/360º) × πr2. θ is the angle that the center subtends. For Ellipse: a x b x π. The answer will come as units squared. For Parallelogram: Multiply its base into height.
