Question

C++ program that computes for the area of a rectangle. There are two set of measurements give below

Rectangle 1 has a length of 8 and a width of 5.
Rectangle 2 has a length of 4 and a width of 20.

Answer 1

#include <iostream>

using namespace std;

int main() {

  int s1m1 = 8;

  int s1m2 = 5;

  int s2m1 = 4;

  int s2m2 = 20;

  cout << s1m1 * s1m2 << " is the area of rectangle 1" << endl;

  cout << s2m1 * s2m2 << " is the area of rectangle 2";  

  return 0;

}

$\huge{\blue{\underline{\mathfrak{Logic-}}}}$

• First of all we included a header file.
• Then we listed the standard namespace.
• C++ ignores white spaces.
• int main is the main method required to run almost every valid program.
• We declared 4 variables with their values respectively.
• Then we printed them using the formulas.
• endl is used for a new line.
• 'return 0;' ends the main method.

Hope it helps...
