Penjelasan dengan langkah-langkah:
L = ((11 + 22) x 8) : 2 + (16 x 12)
L = (33 x 8) : 2 + 192
L = 264 : 2 + 192
L = 132 + 192 = 324 cm2

Bangun 2 = persegi panjang
L trapesium = 1/2 x (jumlah sisi sejajar) x t
L = 1/2 x (11 + 22) x 8
L = 1/2 x 33 x 8
L = 132 cm^2
L persegi panjang = p x l
L = 16 x 12
L = 192 cm^2
Luas gabungan = 132 + 192 = 324 cm^2
