tolong jawab semua nya yah

3.
jarak sebenarnya=
sisi sejajar A ) 12 × 300 = 3600 cm
sisi sejajar B ) 18 × 300 = 5400 cm

selisih panjang = 5400-3600 = 1800cm
= 18m (a)

4.
jarak sebenarnya =
6 × 1200000 = 7200000cm
=72 km (b)

5.
skala =
2.5 cm : 30 km = 2.5 : 3000000
= 1 : 1200000 (d)

6.
Jarak sebenarnya =
p0 = 10m ÷ 20cm = 1000÷20 = 50
L0 = 12cm ×50 = 12 × 50 = 600 cm
= 6 m (b)
