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
