Answer 1

Step: Expressing set G in roster form

In roster form, the elements of the set are written inside a pair of curly braces and are separated by commas.

Names of three closed figures in geometry are triangles, rectangles and pentagons.

Hence, the roster form of set is
G = {Triangle, Rectangles, Pentagons}.
