: For flat shapes, we calculate perimeter (the boundary) and area (the surface size). Examples :

Understanding the transition from flat (plane) shapes to volumetric (solid) bodies is a foundational step in 4th-grade geometry. It bridges the gap between simple drawing and understanding the physical world in three dimensions. ploskie i obieemnye figury 4 klass prezentatsiia
