Question

Write a java program to accept the three sides of a triangle (say a,b and c) and find its

perimeter and area.

i. Perimeter: p = a+b+c

ii. Area: ar = , where s=p/2

Display the results obtained with appropriate messages​

Answer 1

Answer:

import java.util.*;

import java.io.*;

class Triangle

{

public static void main(String a[])

{

Scanner s=new Scanner(System.in)

int a=s.nextInt();

int b=s.nextInt();

int c=s.nextInt();

int p=a+b+c;

float s=p/2;

floar area=s*Math.sqrt(ab+bc+ca);

System.out.println(p+""+area);

}

}
