The class of coabelian subgroups of free groups provided many groups with interesting finiteness properties e.g. the Stallings-Bieri groups. For the finitely presented groups in this family we can study their Dehn functions. Various authors have worked on the case of the Stallings-Bieri groups. Building on these methods we give upper and lower bounds for Dehn functions of certain coabelian subgroups of direct products. This is joint work with Claudio Llosa Isenrich.
