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

#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;

}

Step-by-step 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.
