Answer:
First factor the Area
Area = 18x2+12x+2
Factor out a 2
Area = 2(9x2+6x+1)
Factor this and you get
Area=2(3x+1)(3x+1)
Let L be Length and W be Width
Area=LW
and the Length is twice the Width so
L=2W
Area=2(3x+1)(3x+1) so
L=2(3x+1)
W=3x+1
This can also be written as if you distribute the 2
L=6x+2
W=3x+1
