Area pamphlet (5)
I believe the answer is:
Here is my best explanation:
This clue is a double definition.
'area' is the first definition.
(tract is a kind of area)
'pamphlet' is the second definition.
('tract' can be a synonym of 'pamphlet')
(Other definitions for tract that I've seen before include "Large area; treatise", "Region; pamphlet", "Religious pamphlet", "Pamphlet; area of land", "Stretch of land or religious pamphlet", "Area - pamphlet", "Short treatise; land area", "Area of land", "Expanse of land; treatise" and "Religious treatise".)
