Program to find the area of an equilateral triangle

Explanation

A Triangle is having all angles of 60 degrees and congruent sides, or equiangular triangle is called Equilateral Triangle.

Area of Equilateral Triangle= ( 1.73 × a × a)/4

where a is side.

Algorithm

Define Values for side of triangle
Enter values in formula.
Print the Area.

Complexity

O(1)

Solution

Python

a= 5
area = ( 1.73 * a*a) / 4
print("Area of Equilateral Triangle is: ");
print(area);

Output:

Area of Equilateral Triangle is:  10.8125

C

#include<stdio.h>
                   int main() 
                   { float a, area;
			a= 5;
			area = ( 1.73 * a*a) / 4 ;

			printf("\n\n Area of Equilateral Triangle is : %f",area);
                       return (0);
    }

Output:

Area of Equilateral Triangle is: 10.81250

JAVA

public class tops
 {
   public static void main (String args[])
	{	float a = 5f ; 
                          double area = ( 1.73 * a*a) / 4 ;
System.out.println("Area of Equilateral Triangle is:"+area);
	}}

Output:

Area of Equilateral Triangle is: 10.8125

C#

using System;
class Program
{   static void Main() 
    {
      float  a = 5 ;
      double area =  ( 1.73 * a*a) / 4 ; 
      Console.WriteLine("Area of Equilateral Triangle is :"+area);
    }}

Output:

Area of Equilateral Triangle is: 10.8125

PHP

<?php
       $a = 5 ;
       $area =   ( 1.73 * $a * $a) / 4;
       echo("Area of Equilateral Triangle is: ");
       echo($area);
?>

Output:

Area of Equilateral Triangle is: 10.8125
