nomor 9 sampe abis
#ga pelit point'​

Answer 1

Jawaban:

9. Ts = 6cm x 1/250

= 6 x 250/1

= 1500 cm = 15 m

AS = 12,8 × 1/250

= 12,8 × 250/1

= 3200cm = 32 m

Ls = 32 × 15 = 480 m²

10. bangun I

ps = 6 : 1/300

ps = 6 × 300/1

ps = 1800 cm = 18 m

ls = 5 : 1/300

ls = 5 × 300/1

ls = 1500 cm = 15 m

Ls I = 18 × 15 = 270 m

bangun II

ps = 4 : 1/300

ps = 4 × 300/1

ps = 1200 cm = 12 m

ls = 9 : 1/300

ls = 9 × 300/1

ls = 2700 cm = 27 m

Ls II = 12 × 27 = 324 m

luas seluruh bangunan = 270 + 324 = 594 m²

11. ps = 8 : 1/600

ps = 8 × 600/1

ps = 4800 cm = 48 m

ls = 4 : 1/600

ls = 4 × 600/1

la = 2400 cm = 24 m

Ls= 48 × 24 = 1.152 m

AS = 4:1/600

AS= 4×600/1

AS= 2400 cm = 24 m

ts = 4:1/600

ts=4×600/1

ta=2400cm=24m

Ls = 1/2 × 24 × 24 = 288 m

luas keseluruhan = 1.152 + 288 = 1.440 m²

12. 6 sisi

13. 12 rusuk

14. persegi
