## Abstract

We introduce an area formula for computing the spherical measure of an intrinsic graph of any codimension in an arbitrary homogeneous group.

Our approach only assumes that the map generating the intrinsic graph is continuously intrinsically differentiable. The important novelty lies in the notion of Jacobian, which is built by the auxiliary Euclidean distance.

The introduction of this Jacobian allows the spherical factor to appear in the area formula and enables explicit computations.
