Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete (haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes (diploid).[1] This is typical in animals, though the number of chromosome sets and how that number changes in sexual reproduction varies, especially among plants, fungi, and other eukaryotes.[2][3]
In the first stage of sexual reproduction, meiosis, the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During fertilisation, haploid gametes come together to form a diploid zygote, and the original number of chromosomes is restored.
Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants.[4][5] Sexual reproduction also occurs in some unicellular eukaryotes.[2][6] Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such as bacteria and archaea. However, some processes in bacteria, including bacterial conjugation, transformation and transduction, may be considered analogous to sexual reproduction in that they incorporate new genetic information.[7] Some proteins and other features that are key for sexual reproduction may have arisen in bacteria, but sexual reproduction is believed to have developed in an ancient eukaryotic ancestor.[8]

Perimeter of the garden is 54 m.
Given : -
Breadth of the garden = 9.3 m
Length of the garden = 17.7 m
We know formula),
of the rectangle = 2( length + breadth )
Now, on the basis of the formula given above,
Perimeter of the garden = 2(9.3 m + 17.7 m)
Perimeter of the garden = 2(27 m)
Perimeter of the garden = 54 m
Therefore the perimeter of the garden is 54 m.
