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.
Part A: Express both the length and the width of the rectangle as a function of a side of the square.

Responses
length:l(s)=2y
width:w(s)=y+2
length:l(s)=2+y
width:w(s)=2y
length:l(S)=y^2
width:w(s)=2y
length:l(s)=y^2
width:w(s)=y+2
Part B: Write a function to represent the area of the rectangle in terms of the sides of the square. (1 point) Responses
*A(s)= 2y^2+4y
*A(s)=2y^3+2y^2
*A(s)=3y+2
*A(s)=2y^2+4
*A(s)=6y+4
The correct answer is:
*A(s)= 2y^2+4y
