double length;
cout << "What is the rectangles length? ";

You have the basic structure of your functions wrong, functions can not be defined inside other functions a program calling 1 function might look something like this

#include <iostream>
 
using namespace std;
 
void getLength();
 
int main()
{
  cout << "Main Entered" << endl;
 
  getLength();
 
  cout << "Back in Main, exiting now" << endl;
 
  return 0;
}
 
void getLength()
{
  cout << "getLength called" << endl;
}
