Area

• A quadrilateral with both pairs of opposite sides parallel.
• The number of square units it takes to completely fill a space or surface.
• a polygon having four sides, four angles, and four vertices
• A closed shape. A regular polygon has all sides equal and all interior angles equal. An irregular polygon's sides are not all the same length nor do the interior angles have the same measure.
• Option 5

Base

• A two-dimensional figure that, when folded, forms the surfaces of a three-dimensional object.
• A three-dimensional figure whose base is a polygon and whose other faces are triangles.
• The face of a geometric figure from which the height can be measured.
• A solid (3-dimensional) object, which has six faces that are rectangles.

Net

Rectangular prism

• The face of a geometric figure from which the height can be measured.
• A solid (3-dimensional) object, which has six faces that are rectangles.
• A two-dimensional figure that, when folded, forms the surfaces of a three-dimensional object.

• the points where two or more line segments or edges meet (like a corner).
• The amount of space occupied by an object.
