Question

Consider the getArea method from the textbook shown below:
Public int getArea()
{
If (width <= 0) { return 0; } // line #1
If (width == 1) { return 1; } // line #2
Triangle smallerTriangle = new Triangle(width - 1); // line #3
Int smallerArea = smallerTriangle.getArea(); // line #4
Return smallerArea + width; // line #5
}
If line #1 was eliminated from the method, what would be the result when calling getArea?
A) A negative or zero width would cause problems.
B) Nothing - the method would still work correctly.
C) We would lose our only recursive case.
D) A positive width would reduce the correct area by 1.

If line #1 was eliminated, there would be no check for invalid width values such as negative or zero values. These values would cause problems in computing the area of the triangle, as the width cannot be negative or zero. Therefore, answer choice A is the best choice.
