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.
a(y)=
a(y) = 2y*y + 2(y+2)*y
a(y) = 2y^2 + 2(y^2 + 2y)
a(y) = 2y^2 + 2y^2 + 4y
a(y) = 4y^2 + 4y
