48 m = 4800 cm
36 m = 3600 cm

[tex] \frac{4800}{84} = \frac{3600}{x} \\ \\ 4800x = 302.400[/tex]

[tex]x = \frac{302.400}{4800} \\ \\ x = 63 cm[/tex]

Jawaban : A

___________________________

25 m = 2500 cm

[tex] \frac{10}{2500} = \frac{8}{x } \\ \\ 10x = 20.000 [/tex]

[tex]x = \frac{20.000}{10} \\ x = 2.000[/tex]

2000 cm
= 2000/100
= 20 m

Jawaban : C

15] sayap model/sayap sebenarnya = badan model/badan sebenarnya
Sayap model/36 m = 84 cm / 48 m
Sayap model = 84 . 36 / 48
Sayap model = 63 cm

18] sayap sebenarnya / sayap model = badan sebenarnya / badan model
Sayap sebenarnya / 8 cm = 25 m / 10 cm
Sayap sebenarnya = 8 . 25/10
Sayap sebenarnya = 20 m
