Say you know that a rectangle has an area of (a^2+4a+4) square inches, and you know that the width is (a+2) inches. Use long division to determine the length of the box.

We can't do long division here, I am wondering what your question really is.

Area/width= length

(a^2+4a+4)/(a+2= (a+2)(a+2)/a+2= a+2

looks like a square to me.
Long divison isn't the case for this kind of problem.It looks like a square.
