Asosiy qism:
Biror shaklning yuzini hisoblash deganda uni nechta birlik kvadrat bilan qoplash mumkinligini toppish tushuniladi.
To’g’ri to’rtburchak yuzini toppish uchun uning bo’yini eniga ko’paytirish kifoya.
S=a∙b
Kvadratning yuzi S=a² formula bilan hisoblanadi.
2-misol.
a) a=5 m; b=3 m; S-?
S=a∙b=5∙3=15
b) a=4 dm; b=360 sm=36 dm; S-?
S=a∙b=4∙36=144
d) a=12 sm; b=43 sm; S-?
S=a∙b=12∙43=516
e) a=12 m=120 dm; b=56 dm; S-?
S=a∙b=120∙56=6720
Mustahkamlash:
3-misol.

5-misol.
a=8; S₁=4;
S=8∙8=64; n=64:4=16
6-misol.
