Morphology

two-dimensional + figure

The meaning 'a shape with length and width but no depth' is directly and compositionally derived from the adjective 'two-dimensional' (flat, no depth) modifying the noun 'figure' (shape). This adjective+noun construction follows regular English compositional rules and is cross-linguistically common, so a B1 learner who knows both constituents will readily infer the MWE meaning.

Etymology

Two-dimensional figure comes from geometry: two means two directions and dimensional means those directions, while figure means a shape. Imagine a drawing on flat paper that has 'length' and 'width' but no 'depth', so the phrase means a shape with only length and width and no depth.
