The figure shows a square of side $y$ units divided into a square of side $x$ units and four congruent rectangles. What is the perimeter, in units, of one of the four congruent rectangles? Express your answer in terms of $y$.
Hint: The width + length of the rectangle is equal to \(y\).
Perimeter = width + length + width + length. I just gave you what width + length equals.
