width=x
length=3x-2
half perimeter is their sum, or 4x-2
perimeter is 8x-4
--
The center rectangle loses 4 feet (2 on each side) for the length and width.
the width of that is x-4
the length is 3x-6, subtracting feet only not 3x-2, since that only defines the ratio of the outer part.
half perimeter is the sum of 4x-10
perimeter is 8x-20</PRE>
