Jawab:
A. 288 cm²
Penjelasan dengan langkah-langkah:
L1 Trapesium = 1/2 x (a +b) x t
L1 Trapesium = 1/2 x (8 + 24) x 12
L1 Trapesium = 1/2 x32 x 12
L1 Trapesium = 1/2 x 384
L1 Trapesium = 192 cm²
L2 Segitiga = 1/2 x a x t
L2 Segitiga = 1/2 x 12 x 16
L2 Segitiga = 1/2 x 192
L2 Segitiga = 96 cm²
Luas total = 192 cm² + 96 cm² = 288 cm²
