Question

Develop a program that will calculate the area and perimeter of a rectangle. The length and width can be given as constant.(LENGTH= 8 WIDTH=8).

Answer 1

Answer:

#include <iostream>

using namespace std;

int main()

{

 

  int length = 8;

  int width = 8;

 

  int perimeter = 2*(length + width);

  int area = length * width;

 

  cout<<"The perimeter is "<<perimeter<<endl;

  cout<<"The area is "<<area<<endl;

 

  return 0;

}

Explanation:

include the library iostream for using the input/output instructions in the c++ programming.

Create the main function and define the variable length and width with values.

Then, use the formula for calculating the perimeter and area of rectangle.

$perimeter = 2*(length + width)$

$area = length * width$

and store in the variables and finally print the output.
