Program to calculate area and perimeter of a rhombus whose diagonals are given
• Last Updated : 18 Mar, 2021

Given the length of diagonals of a rhombus, d1 and d2. The task is to find the perimeter and the area of that rhombus.
A rhombus is a polygon having 4 equal sides in which both the opposite sides are parallel, and opposite angles are equal. Examples:

Input: d1 = 2 and d2 = 4
Output: The area of rhombus with diagonals 2 and 4 is 4.
The perimeter of rhombus with diagonals 2 and 4 is 8.

Input: d1 = 100 and d2 = 500
Output: The area of rhombus with diagonals 100 and 500 is 25000.
The perimeter of rhombus with diagonals 100 and 500 is 1019.

Area of the rhombus = Perimeterof the rhombus = Below is the implementation of above approach:

## C++

## Javascript

 
Output:
The area of rhombus with diagonals 2 and 4 is 4.
The perimeter of rhombus with diagonals 2 and 4 is 8.
