I have attached a picture of the problem. As you can see, I have already tried to solve the problem, but to no avail. I cannot figure it out at all. Any ideas?

The answer is to be in terms of y.

Every point ont your line is $\displaystyle (4-2y,y)$

The width is $\displaystyle 4-2y$ and the length is $\displaystyle y$.
