No bother working for figure (7)

Ross

I believe the answer is:

nonagon

'for figure' is the definition.
(shape or figure with 9 sides)

'no bother working' is the wordplay.
'bother' becomes 'nag' (I've seen this in another clue).
'working' becomes 'on' (on can mean working or activated).
'no'+'nag'+'on'='NONAGON'

(Other definitions for nonagon that I've seen before include "Nine sided figure" , "Nine-sided polygon" , "geometric figure" , "regular figure" , "Nine-sided shape" .)

I've seen this clue in The Telegraph.
