For a definition of "wapentake", see the article entitled Hundred (county division) in Wikipedia.
Wapentakes, the Old Norse form of the Anglo-Saxon "hundred", are dealt with in Section 1.4, but Sections 1.1 (Hundred courts) and 1.2 (Administrative functions) deal with the concept and purposes of wapentakes along with those of "hundreds" used in English counties further south.
Rydale Wapentake was located in the centre of the eastern half of the North Riding of Yorkshire. It was bounded by Langbargh Wapentake on the north, Pickering Lythe on the east, Bulmer on the south, and Birdforth on the west.
