Question

Pick out the noun and tell the kind of each one

Answer 1

Answer:

The name given to every person or thing of the same class or kind is a common noun. The name given to a quality, action or state considered apart from the object to which it belongs, is an abstract noun.

Room and Feet are common names, hence they are common nouns and length is a measure of distance which is intangible. Hence, it is an abstract noun.
