The area is not *directly* proportional to the side length of a square.
A = s²
For example:
Side = 1 inch --> Area = 1 sq. inch
Side = 2 inches --> Area = 4 sq. inches
Side = 3 inches --> Area = 9 sq. inches
Side = 4 inches --> Area = 16 sq. inches
It isn't being multiplied by a constant and is not a linear relationship; it's being squared. All the rest are likely to be directly proportional.
