Programming Examples
Java program to input the length and breadth of a rectangle and find its area and perimeter
Write a program to input the length and breadth of a rectangle and find its area and perimeter.
Note:
Area of a rectangle=length*breadth
Perimeter of a rectangle=2*(length+breadth)
Solution
import java.util.*;
class Demo
{
public static void main(String arr[])
{
Scanner sc=new Scanner(System.in);
float l,b,a,p;
System.out.println("Enter the length:");
l=sc.nextFloat();
System.out.println("Enter the breadth:");
b=sc.nextFloat();
a=l*b;
p=2*(l+b);
System.out.println("Area="+a);
System.out.println("Perimeter="+p);
}
}
Output
Write a program to input the length and breadth of a rectangle and find its area and perimeter.
Note: Area of a rectangle=length*breadth
Perimeter of a rectangle=2*(length+breadth)
Solution
import java.util.*;
class AreaPerimeter
{
public static void main(String arr[])
{
Scanner sc=new Scanner(System.in);
float l,b,a,p;
System.out.println(“Enter the length:”);
l=sc.nextFloat();
System.out.println(“Enter the breadth:”);
b=sc.nextFloat();
a=l*b;
p=2*(l+b);
System.out.println(“Area=”+a);
System.out.println(“Perimeter=”+p);
}
}
Output
Write a program to input the length and breadth of a rectangle and find its area and perimeter.
Note: Area of a rectangle=length*breadth
Perimeter of a rectangle=2*(length+breadth)
