Question

664. To'g'ri to'rtburchak shaklidagi tomorqaning eni 60 m, bo'yi 70 m. Uning yuzini toping va arda ​

Answer 1

Ответ:

1dm=10sm 64dm=640sm

Yechish:640-(18•2)=640-36=614

614:2=307

Javob:307sm

Answer 2

Tomorqa yuzini topish uchun yuzi formula yordamida hisoblaymiz:

Yuzi (A) = Eni (l) * Bo'yi (w)

A = 60 m * 70 m = 4200 kvadrat metr.

Shunday qilib, to'g'ri to'rtburchak shaklidagi tomorqaning yuzi 4200 kvadrat metr.
