Jawaban:
✨Lp = 2 ( p × l + p × t + l × t)
1. ☁Diketahui:
p = 20 cm
l = 6 cm
t = 8 cm
☁Jawab:
Lp = 2 ( 20 × 6 + 20 × 8 + 6 × 8 )
Lp = 2 ( 120 + 160 + 48 )
Lp = 2 × 328
Lp = 656 cm²
2. ☁Diketahui:
p = 12 cm
l = 8 cm
t = 15 cm
☁Jawab:
Lp = 2 ( 12 × 8 + 12 × 15 + 8 × 15 )
Lp = 2 ( 96 + 180 + 120 )
Lp = 2 × 398
Lp = 792 cm²
3. ☁Diketahui:
p = 20 cm
l = 15 cm
t = 8 cm
☁Jawab:
Lp = 2 ( 20 × 15 + 20 × 8 + 15 × 8 )
Lp = 2 ( 300 + 160 + 120 )
Lp = 2 × 580
Lp = 1.160 cm²
