Program to calculate area and perimeter of a rhombus whose diagonals are given

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++

// 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;
}

    perimeter = (int)(2 * Math.sqrt(Math.pow(d1, 2) + Math.pow(d2, 2)));

    System.out.println( "The area of rhombus with diagonals "
