Area.
Very few 2-dimensional figures can be measured by length and width - rectangles (and stretching the terminology) triangles and parallelograms. Certainly not circles, stars, irregular polygons, other irregular shapes.
Area; this is often measured in square meters, or square centimeters.
Volume - measured in cubic meters, cubic centimeters, etc.APEX height, length, and width
Congruent figures are always similar. However, similar figures are only sometimes congruent.
Coplanar figures.
2-D means twodimensional. Meaning, in this case, that no special effort has been made to give a 3-D (threedimensional) appearance. A 3-D film would have you make special glasses, which show a different image to each eye - stereoscopic (3-D) vision is based in great part on the fact that our two eyes see slightly different images.2-D means twodimensional.

4 significant figures.
Volume - measured in cubic meters, cubic centimeters, etc.APEX height, length, and width
All three of them are significant figures
They can be measured by their linear measures in three orthogonal directions.
