Let’s learn area of isosceles triangle in java.

## Area of Isosceles Triangle in java

An isosceles triangle is a triangle where its two sides and angles are equal. To calculate area of isosceles triangle formula is:

area of isosceles triangle = [ B/4√((4 * a * a) – (b * b)) ]

Now let’s see java program.

import java.util.Scanner; public class AreaOfIsoscelesTriangle { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("Please enter length of same sided: "); double a = sc.nextDouble(); System.out.println("Please enter side2 of isosceles triangle: "); double b = sc.nextDouble(); double area = (b/4) * Math.sqrt((4 * a * a) - (b * b)); System.out.println("Area of isosceles triangle is: " + area); sc.close(); } }

**Output:**

Please enter length of same sided:

6

Please enter side2 of isosceles triangle:

9

Area of isosceles triangle is: 17.858821349685986
