Smart Math Formula Rhombus,  a Rhombus is a four sided polygon in which every side has the same length. 

Rhombus Formula : It is an equilateral quadrilateral.

Base Times Height Method : Area of Rhombus = b . h

Diagonal Method : Area of Rhombus = ½ . d1 . d2

Perimeter of Rhombus = 4 . [a]

Note :
a = side, b = breadth, h = height, d1, d2 [Are diagonals Rhombus]

Example

Question: Find the area of a rhombus with the given base 6 and height 8 using Base Times Height Method.

Question: Find the area.

Area = b . h = 6 . 8 = 48

Question: Find the perimeter of a rhombus with the given side 6.

Question: Find the perimeter.

Perimeter = 4 . [a] = 4 . 6 = 24.

That example will clearly illustrates how to calculate the Area, Perimeter of a Rhombus manually.
