double length=10;

double breadth=length/2;

double perimeter=2*(length+breadth);

System.out.println("perimeter of rectangle "+perimeter);

double area=length*breadth;

System.out.println("area of rectangle "+area);

}

}

#include<iostream>

using namespace std;

int main(){

double length=10;

double breadth=length/2;

double perimeter=2*(length+breadth);

cout<<perimeter;

double area=length*breadth;

cout<<area;

return 0;
