This seems like a poor choice. In three dimensions, of course, there's an interesting theory of equidecomposability for polyhedra, which does not reduce to just computing volumes.
What's wrong with the obvious term "equalarea"? As in "Any two triangles with the same base and height are equalarea triangles." Seems precise and clear; what more would you want?
