Let’s learn area of equilateral triangle in java.

## area of equilateral triangle in java

An equilateral triangle is geometrical shape where its three sides are equal. Formula to calculate area of equilateral traingle is –

area of equilateral triangle: √3/4 x s²

where ‘s’ is side of equilateral triangle.

Here’s the program to find area of an equilateral triangle in java.

import java.util.Scanner; public class AreaOfEquilateral { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("Please enter the side of equilateral triangle: "); double side = sc.nextDouble(); double area = (Math.sqrt(3)/4) * (side * side); System.out.println("Area of equilateral triangle is: " + area); sc.close(); } }

**Output:**

Please enter the side of equilateral triangle: 6

Area of equilateral triangle is: 15.588457268119894
