Step-by-step explanation:   because in the sense that the new area could be written as (x+1)^2  /   1.

Usually we would not bother with the "1" as divisor.

Let's actually do the work:  what is the area of the square if we increase the side length of the existing square by 1 ft?

(x+1)^2 = x^2 + 2x + 1        (This is not a fraction, and thus not the ratio of

                                           two integers, which, in turn, is the definition of

                                           "rational number."
