Write a Program to calculate the Area of Rhombus

Before writing the program of calculating the area of rhombus in different programming languages, firstly we have to know about what is rhombus and what is the formula to find area of it?

What is Rhombus?

A rhombus is a polygon, whose all four sides is equal in length and opposite side is parallel.

Area of Rhombus = ( d1 * d2 ) / 2
Where, d1 and d2 are the two diagonals of rhombus. 

Program of calculating the area of a rhombus in different Programming languages

Program 1: Write a Program in C language:

// This a C program which uses a function to find the area of a rhombus.
#include <stdio.h> // Function to find area 
float findAreaofrhombus(float d1, float d2) 
{ 
float Area_of_rhombus;
Area_of_rhombus= ( d1 * d2 ) / 2; // It is a formula for calculating a area of rhombus 
return (Area_of_rhombus); 
} 
int main() 
{ 
float d1, d2; 
printf("Enter the 1st diagonal of the rhombus:"); 
scanf("%f",&d1);
printf("Enter the 2nd diagonal of the rhombus:");
scanf("%f",&d2);
printf("Area of the rhombus is: %.2f", findAreaofrhombus(d1, d2));   
return 0; 
}

Output of Above C program:

Enter the 1st diagonal of the rhombus:5
Enter the 2nd diagonal of the rhombus:10
Area of the rhombus is: 25.0

Program 2: Write a Program in Java language:

// This a  Java program which calculates the area of a rhombus.
class findarea { 
static int findAreaofrhombus(int d1, int d2) 
{ 
int Area_of_rhombus;
Area_of_rhombus= ( d1 * d2 ) / 2; // It is a formula for calculating the area of rhombus 
return(Area_of_rhombus); 
} 

// Driver method 
public static void main(String[] args) 
{ 
int d1 = 20;
int d2 = 40; 
System.out.println("The Area of a rhombus in Java:");
System.out.println(findAreaofrhombus(d1, d2)); 
} 
}

Output of Above Java program:

The Area of a rhombus in Java:
400

Program 3: Write a Program in PHP programming language.

<?php 
// This a  PHP program which calculates the area of a rhombus.  
// Function to find area 
function findAreaofrhombus($d1, $d2) 
{         
$Area_of_rhombus = ( $d1 * $d2 ) / 2; // It is a formula which calculates the area  and store the value in the area variable. 
return ($Area_of_rhombus); 
} 

$d1 = 80;  
$d2= 30; 

echo findAreaofrhombus($d1, $d2); 

?>

Output of Above PHP program:

Program 4: Write a Program in Python programming language.

# This is a python program which calculates the area of a rhombus. 
# It is a function to calculate the area of rhombus
def findAreaofrhombus(d1, d2):
    return ( ( d1 * d2 ) / 2) # It is a formula which adds the three side and # then return the value to the statement of calling fucntion. 
d1 =30
d2= 40
print(findAreaofrhombus(d1,d2))

Output of Above Python program:
