Bantu 1-6 dong gengs pakai caraa yaaa

1) dik : s = 1:1.500.000
jp = 12 cm

js = s × jp
= 1.500.000/1 × 12
= 18.000.000 : 100.000
= 180 km →→ a. ✓✓✓

2) dik : p = 20 cm → 0,2 m
l = 14 cm → 0,14 m
s = 1:500

p = 500/1 × 0,2
= 100 m

l = 500 × 0,14
= 70 m

jadi, L = p × l
= 100 × 70
= 7.000 m² →→b. ✓✓✓

3) 12 cm : 1 1/3 m
= 12/1 : 4/3 m
= 12 × 3/4
= 9 : 100 m →→ c. ✓✓✓

semoga membantu......

1 ) Jarak sebenarnya = Jarak pada peta ÷ Skala
= 12 cm ÷ 1/1.500.000
= 12 cm × 1.500.000
= 18.000.000 cm
= 180 km

2 ) Panjang
= 20 cm ÷ 1/500
= 20 × 500
= 10.000 cm
= 100 m
Lebar
= 14 cm ÷ 1/500
= 14 × 500
= 7000 cm
= 70 m
Luas = p × l
= 100 × 70
= 7000 m2

4 ) 6 km/jam : 40 m/menit
6 km/jam = 6000 m/60 menit = 100 m/menit

= 100 m/menit : 40 m/menit ( sama2 dibagi 20 )
= 5 : 2
