figure

I'm a little stuck... Click here to teach me more about this clue!

'shape?' is the definition.
(figure is a kind of shape)

I don't understand how the rest of the clue works.

(Other definitions for figure that I've seen before include "Person's bodily shape" , "Reckon" , "Consider" , "movement by skater" , "Judge to be probable, estimate" .)

I've seen this clue in the Evening Standard.
