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)
