The sides of a square all have a side length of y. Write a simplified area function in terms of
y for a rectangle whose length is twice the side length of the square and whose width is 2 units longer than the side length of the square.
The length of the rectangle is 2y and the width is y + 2.
The area of a rectangle is given by the formula A = length x width.
Therefore, the area function in terms of y for this rectangle is:
A = (2y)(y + 2)
A = 2y^2 + 4y
