#include <stdio.h>

int main() {
  int s = 14 ;
  int area = 14 * 14;
  int cost =  * 7;
  printf("%d /n", area);   //Area and cost have to be output on separate lines
  printf("%d",cost );      //'$' has to be printed after cost without any space

}

MY SOLUTION IN C++

#include <bits/stdc++.h>
using namespace std;

int main() {
  int s = 14;
  int area = (s * s);
  int cost = ((area) *7);
  cout << area << endl;     //area and cost have to be output on separate lines
  cout << cost<<"$";             //output the $ character after cost without any

  
  
  return 0;
