Area pamphlet (5)
I believe the answer is:
tract
I believe 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 "Religious treatise" , "Publication" , "Stretch of land or religious pamphlet" , "Pamphlet, large expanse of land" , "Large area; treatise" .)
