// ^ after computing the area, "return" it
}
}
// The output is technically the same for both.
// The line count for the program with methods is 30 while the one without is 50.
// It was much easier to fix the bug in the file with a method because it only requires you to change one value intsead of changing each value individually.
// It was very easy to add the new test becuase I didn't have to write the whole code for finding the area.
