Calculate the area, perimeter of Rhombus (Rhombus Calculator)  
 
 
 

Diagonal Method :
Area of Rhombus = ½ * d1 * d2
Trigonometry Method :
Area of Rhombus = a² * SinA
Perimeter of Rhombus = 4(a)
where,
a = side, b = base, h = height, d1, d2 are diagonals
Examples:
Case 1: Find the area of a rhombus with the given base 4 and height 5 using Base Times Height Method.
Step 1: Find the area.
Area = b * h = 4*5 = 20.
Case 2: Find the area of a rhombus with the given diagonals 4,5 using Diagonal Method.
Step 1: Find the area.
Area = ½ * d1 * d2 = 0.5 * 4*5 = 20*0.5 = 10
Case 3: Find the area of a rhombus with the given side 3 using Trigonometry Method.
Step 1: Find the area.
Area = a² * SinA = 3² * Sin(33) = 9* 1 = 9.
Case 4: Find the perimeter of a rhombus with the given side 3.
Step 1: Find the perimeter.
Perimeter = 4(a) = 4 * 3 = 12.
