I guess you need solution on C++. Here is the code:

int main () {    double areaofsquare;    double length    cin >> areaofsquare;
length = sqrt(areaOfSquare);
 
std::cout << length << std::endl;       if(areaofsquare >= 0)    {     sqrt(areaofsquare);     cout << areaofsquare << endl;          }      else     { cout << "INVALID" << endl;              } 
      }
