Verified answer

Bangun I = persegi panjang
Bangun II = Trapesium

Luas bangun I
L = panjang x lebar
L = 43 x 44
L = 1.892 cm2

Luas bangun II
tinggi = 82 - 44 = 38 cm
L = 1/2 x (jumlah sisi sejajar) x tinggi
L = 1/2 x (15 + 43) x 38
L = 1/2 x 58 x 38
L = 29 x 38
L = 1.102 cm2

Luas segi banyak
L = 1.892 + 1.102 = 2.994 cm2
