Penjelasan dengan langkah-langkah:
Panjang = 15 cm
Lebar = 2 cm
Tinggi = 8 cm
Lp = 2(pl + pt + lt)
Lp = 2(15x2 + 15x8 + 2x8)
Lp = 2(30 + 120 + 16)
Lp = 2 x 166
Lp = 332 cm² Jawabannya
Lp = 2(p × l + p × t + l × t)
Lp = 2(15 × 2 + 15 × 8 + 2 × 8)
Lp = 2(30 + 120 + 16)
Lp = 2(30 + 136)
Lp = 2(166)
Lp = 332 cm²
