Measures to make cheaters look silly (8)
I believe the answer is:
hectares
'measures' is the definition.
(hectare is a kind of measure)
'cheaters look silly' is the wordplay.
'look silly' indicates anagramming the letters (I've seen this in other clues).
'cheaters' anagrammed gives 'HECTARES'.
'to make' is the link.
(Other definitions for hectares that I've seen before include "Metric measures for land" , "Square measures" , "areas of land" , "Metric units of land measurement" , "Metric measures of areas" .)
