An area leaflet (5)
I believe the answer is:
tract
I believe this is a double definition.
'an area' is the first definition.
(tract is a kind of area)
'leaflet' is the second definition.
(I've seen this in another clue)
(Other definitions for tract that I've seen before include "Lots of land" , "Printed leaflet" , "Region; pamphlet" , "Expanse of land; treatise" , "Stretch of space or time" .)
