Question

IN C++ LANGUAGE PLEASE::: Design and implement a program (name it Rectangle) to calculate and display the area and perimeter of a rectangle with width = 4 and height = 8.

Answer 1

#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
   //declare the width and height and initialize
   //width to 4 and height to 8
   //since rectangle is a geometrical figure so width and height
   //are declared as double.
   double width=4,height=8;   
   double area,perimeter;//declare area and perimeter
   //compuet the area of rectangle
   area = width * height;
   //compuet the perimeter
   perimeter = 2 * (width + height);
   cout<<endl<<"Width of Rectangle : "<<width;
   cout<<endl<<"Height of rectangle : "<<height;
   //print the area and perimeter
   cout<<endl<<"Area of rectangle : "<<fixed<<setprecision(2)<<area<<" Sq. Units.";
   cout<<endl<<"Perimeter of Rectangle : "<<fixed<<setprecision(2)<<perimeter<<" Units.";
   }
