Program to find the area of an equilateral triangleExplanationA 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
ComplexityO(1) SolutionPythona= 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 JAVApublic 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
