int method(cv::Size var1){
    int a,b,c = var1.area();
    return a,b,c;
}

int main(){
  cv::Size var1(300,150);
  int ret = method(var1);

  return ret;
}

Also please tell me what does area() return. Why does area() return three variables?

What I have tried:

I tried googling but didnt find any solution there. Also openCV documentation is not well written.

Try to think: "What does 'area' means when you have a 'size'?" ;-)

Start reading a tutorial, for instance: OpenCV-Python Tutorials — OpenCV-Python Tutorials 1 documentation[^].

It doesn't. As matter of fact, it returns a double (see, for instance Size[^]).
In

C++

int method(cv::Size var1){
int a,b,c = var1.area();
return a,b,c; }

a, b are irrelevant you may (should) remove them (see the 'comma operator' section in Other operators - cppreference.com[^]).
