Berilgan: Formula: Yechish :
m= 150 g = 150 :1000 = 0,15 kg. a= a= . =666,67
Topish kerak: a - ?
Javob: 666,67 .

2-masala.

Chizmasi: Berilgan: Formulalar:
c a= 12cm Gipotenuza : c=
b b=9cm Perimetr : =a+b+c
a Yuza: = ab .
Yechish:
Pifagor teoremasi : c = = + ( 9cm) ) = =15cm
U holda : = 12cm + 9cm +15cm = 36cm = ½ (12cm * 9cm ) = 54 cm2
Javob: 36cm va
