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.
 

Rhombus

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 = \frac{1}{2} (d1 * d2)
Perimeterof the rhombus = 2\sqrt{(d1)^2+(d2)^2}

Below is the implementation of above approach:
 

C++




// C++ Program to calculate area and perimeter
// of a rhombus using diagonals
#include <iostream>
#include <math.h>
using namespace std;
 
// calculate area and perimeter of a rhombus
int rhombusAreaPeri(int d1, int d2)
{
    long long int area, perimeter;
 
    area = (d1 * d2) / 2;
    perimeter = 2 * sqrt(pow(d1, 2) + pow(d2, 2));
 
    cout << "The area of rhombus with diagonals "
         << d1 << " and " << d2 << " is " << area << "." << endl;
 
    cout << "The perimeter of rhombus with diagonals "
         << d1 << " and " << d2 << " is " << perimeter << "." << endl;
}
 
// Driver code
int main()
{
 
    int d1 = 2, d2 = 4;
    rhombusAreaPeri(d1, d2);
 
    return 0;
}

Java




// Java program to calculate area and perimeter
// of a rhombus using diagonals
import java.io.*;
 
class GFG {
   
// calculate area and perimeter of a rhombus
static int rhombusAreaPeri(int d1, int d2)
{
     int area, perimeter;
 
    area = (d1 * d2) / 2;
    perimeter = (int)(2 * Math.sqrt(Math.pow(d1, 2) + Math.pow(d2, 2)));
 
    System.out.println( "The area of rhombus with diagonals "
        + d1 + " and " + d2 + " is " + area + ".");
 
    System.out.println("The perimeter of rhombus with diagonals "
        +d1 + " and " + d2 + " is " + perimeter + ".");
        return 0;
}
 
// Driver code
 
 
    public static void main (String[] args) {
        int d1 = 2, d2 = 4;
    rhombusAreaPeri(d1, d2);
    }
}
