The following post provides the formulae for areas of the quadrilaterals such as Parallelogram, Square, Rhombus, Trapezium and a regular hexagon

**For a parallelogram:** The example of Parallelogram includes, Rectangle, Square, Rhombus and Rhomboid

- Area =Base x Height = Product of 2 slides x sine of included angles
- Diagonal bisect each other

**For a Rectangle:**

- Area = Length x Breadth
- Perimeter = 2 (Length + Breadth)
- Diagonal are equal and bisect each other

**For a Square**

- Area = (Side)
^{2} - Perimeter = 4 x (side)
- Diagonal = Sq root of (2) x Side
- Diameter of Inscribed circle = Side
- Diameter of Circumscribed circle = Diagonal
- Diagonal are equal and bisect each other at right angle (90
^{o}) - Area = Half of (Diagonal)
^{2}

**Rhombus**

- Diagonal bisect each other
- Area = Half of d
_{1}x d_{2}

**Kite **

Area = Half of Product of Diagonal

**Trapezium**

Median = half of (Sum of Parallel Sides)

Area = Half of Sum of parallel Side x Height

**Hexagon**

- Perimeter = 6 x side
