18 "Origami' is the art of paper folding, which is often associated with Japanese culture.
Gurmeet is trying to learn origami using paper cutting and folding technique. A square
base is sometimes referred to as a 'preliminary base or preliminary fold.
Here is a 20cm x 20cm square. Gurmeet wants to first cut the squares of integral length
from the corners and by folding the flaps along the sides.

Answer:
Origami (折り紙, Japanese pronunciation: [oɾiɡami] or [oɾiꜜɡami], from ori meaning "folding", and kami meaning "paper" (kami changes to gami due to rendaku)) is the art of paper folding, which is often associated with Japanese culture. In modern usage, the word "origami" is used as an inclusive term for all folding practices, regardless of their culture of origin. The goal is to transform a flat square sheet of paper into a finished sculpture through folding and sculpting techniques. Modern origami practitioners generally discourage the use of cuts, glue, or markings on the paper. Origami folders often use the Japanese word kirigami to refer to designs which use cuts.

The folding of an Origami crane

A group of Japanese schoolchildren dedicate their contribution of Thousand origami cranes at the Sadako Sasaki memorial in Hiroshima.
The small number of basic origami folds can be combined in a variety of ways to make intricate designs. The best-known origami model is the Japanese paper crane. In general, these designs begin with a square sheet of paper whose sides may be of different colors, prints, or patterns. Traditional Japanese origami, which has been practiced since the Edo period (1603–1867), has often been less strict about these conventions, sometimes cutting the paper or using nonsquare shapes to start with. The principles of origami are also used in stents, packaging, and other engineering applications.[1][2]
Answer:
10 squares of dimensions 2cm × 2cm can Gurmeet make. Hence, Option (iii) is correct.
Step-by-step explanation:
origami, also called paper folding, the art of folding paper objects to create both two-dimensional and three-dimensional objects. The word origami (from the Japanese oru [to fold] and kami ["paper") has become a general description of the art form, although some European historians believe that it gives undue weight to the Japanese origins of the art, which may well have independently developed around the world.
While shearing has traditionally been a part of origami, most modern practitioners—often called "folders"—avoid shearing (although it continues to be used in the Rococo style of linked cranes). Most origami is made of square paper and a single sheet. However, rectangles and other non-square sheets can also be used, and folded and modular origami styles use multiple sheets (even hundreds of sheets can be used in a single artwork).
Creating paper models can require very few resources and take mere minutes (or even seconds) to complete. Complex designs, on the other hand, can take hours. Some folders favor almost cartoonish renderings of their subjects, using simple folding sequences, while others strive for highly accurate representations that require advanced techniques. The use of graphic signs, symbols, and arrows allows folding sequences to be accurately described and thus duplicated, meaning that this art form can be learned independently of language.
Components generally do not compete with each other except to reach new heights of creativity. Creative competitions involve different degrees of competitiveness. Enthusiasts tend to share their work freely, although the time required to diagram each creation means folders can easily accumulate large backlogs of non-diagrammed work. With regard to the commercial use of origami, copyright law has been applied to protect the rights of creators.
Hence, 10 squares of dimensions 2cm × 2cm can Gurmeet make. Hence, Option (iii) is correct.
