Question

Tolong jawab no 11,12,13,14 & 15

Answer 1

11. 1/8
12. 4/9
13. 3/10
14. 1 3/5
15. Lebar sebenarnya = 2×200 = 400
Panjang sebenarnya = 3×200=600
p×l= 400×600 = 240.000

Maaf kalau salah

Answer 2

11. 3/4 : 6 = 3/4 : 6/1 = 3/4 x 1/6 dikecilkan menjadi 1/4 x 1/2 = 1/8 atau 0.125 atau 12.5%

12.2/6 : 3/4 = 2/6 x 4/3 = 8/18

13.3/5 : 2 1/3 = 3/5 : 7/3 = 3/5 x 3/7 = 9/35

14.4/5 : 1/3 : 3/4 = 4/5 x 3/1 = 12/5 : 3/4 = 12/5 x 4/3 dikecilkan menjadi 4/5 x 4/1 = 16/5 = 3 1/5 atau 320% atau 3,2

15.P = 3, L = 2
Rumus = Jarak Peta : Skala = 3/1 : 1/200 = 3/1 x 200/1 = 600 cm Panjang
Rumus = Jarak Peta : Skala = 2/1 : 1/200 = 2/1 x 200/1 = 400 cm Lebar
Rumus Luas = P x L = 600 x 400 = 240.000 CM
