I'm not sure exactly what you want, but your program might look something like this:

Code:
//Price per Parcel

#include <iostream>

using namespace std;

int main()
{
    int length , width , price , sq_feet , total , acreage;
    
    //Use cout to ask user for length
    cin >> length;
    
    //Use cout to ask user for width
    cin >> width;
    
    //Use cout to ask for the price per square foot
    cin >> price;
    
    length * width == sq_feet;
    
    acreage = sq_feet / 43560;
    
    total = sq_feet * price;
    
    //Send sq_feet to cout
    //Send acreage to cout
    //Send total (price) to cout

    return 0;
}
Maybe if you explain it a little better it would be easier to help. (Sorry, I think I'm sounding a bit like shabbir in saying that.)
