Answer 2

Hi!

So the language that has longer sentences and a greater variety of words is formal language.

Step-by-step explanation:

Formal language is mostly designed for situations in which natural language is unsuitable. The symbols and formulas of such languages stand in precisely specified syntactic and semantic relations to one another.

This kind of language has a greater variety of words, so therefore, longer sentences are formed.
