Tolong bantu dong kak plsssssss
Penjelasan dengan langkah-langkah:
(a)
p = 6
l = 3
t = 4
L = 2 × (pl + pt + lt)
L = 2 × ((6×3) + (6×4) + (3×4))
L = 2 × (18 + 24 + 12)
L = 2 × 54
L = 108 cm²
(b)
p = 7
l = 2
t = 3
L = 2 × (pl + pt + lt)
L = 2 × ((7×2) + (7×3) + (2×3))
L = 2 × (14 + 21 + 6)
L = 2 × 41
L = 82 cm²
