How are a symbol and a model both examples of a representation?

Representation is a defined description or portrayal of any object, person, or anything.

The symbols and models are examples of representation.

Symbols are used as a representation in the form of signs, marks, or images to portray the object or anything. For instance, the symbols such as Ag and Au are used to represent Silver and Gold, respectively.

A model is also a structural or diagrammatical representation of a large object or structure. For example, architects build up maps and charts for the design of the building.

Thus, the symbols and models are used as representations for several things, items, structures, and many more.

A symbol and a model are both examples of a representation because they are presented in place of the real thing.

Explanation:

A symbol is a sign, a letter, mark, token, figure, or image used to stand in place of an object, function, or process.  For example, co2 is used in Chemistry to represent carbon dioxide.  There are many symbols representing other objects or meanings.  Mathematically, we can state that "a" equals 40.  "a" is a symbol representing the numerical value "40." Similarly, a model is a representation of a structure or a person on a smaller scale.  For example, Architects produce models of buildings and other projects that they design.
