Answer:
No.
Explanation:
No, writing "are a" in a sentence is not correct because ''are '' is used for plural objects or things such these are boys, footballs are big etc while n the other hand, ''a'' is used for singular objects such as a ball, a boy etc so these two words which are used in separate sentences not in a single sentence with each other. so we can say that we can't write "are a" in a single sentence.
