LP prisma = 2LA + (K × t)
LA = 1/2 × a × b
K = a + b + c (c sisi alas terpanjang)

2LA
2 . 1/2 . 15 . 20
= 300 cm²
K × t
(15 + 20 + 25) × 30
60 × 30
= 1800 cm²

LP = 2(LUAS ALAS) + (K.ALAS + T)
= 2(1/2(15(20) + (15 + 20 + 25)(30)
= 2(1/2(300) + (35 + 25)(30)
= 2(300/2) + (60(30)
= 2(150) + 1.800
= 300 + 1.800
= 2.100 CM²
