This is linear in one variable and without any careful analysis needed.

What is unknown? The lot area.
x, area

Depends. If the variable represents the area of the lot, then it is a linear relationship. If the variable represents one dimension of the lot and it is multiplied by a linear function of that variable representing the other dimension of the lot, then you do have a quadratic function. If you have two variables then you have a 2nd-degree multi-variate function. The point is, next time you ask us a question, please tell the whole story.
