Jawaban:
396 cm²
Penjelasan dengan langkah-langkah:
t = 7 cm
p = 12 cm
l = 6 cm
Lp = 2pl + 2pt + 2lt
Lp = (2 × 12 × 6) + (2 × 12 × 7) + (2 × 6 × 7)
Lp = (24 × 6) + (24 × 7) + (12 × 7)
Lp = 144 + 168 + 84
Lp = 312 + 84
Lp = 396 cm²
2(pl×pt×pt)
a.2 (6.4+6.2,5+4.2,5)
2 (24+15+10)
2(49)=98 cm
b.2 (8.25+8.10+25.10)
2 (200+80+250
2 (530)=1060 cm
c.1dm=10cm jadi 4dm=40cm >panjang
2 (40.20+40.15+20.15)
2 (800+600+300)
2 (1700)=3400 cm
maaf kalau salah
