1. 40 mm^2=... dam^2 2. 32 are=... hektare

1. 0.0000004 dam^2, 2. 0.32 hektare

Pembahasan

1. Mengubah mm^2 ke dam^2:
   1 dam = 10000 mm
   1 dam^2 = (10000 mm)^2 = 100.000.000 mm^2
   Jadi, 40 mm^2 = 40 / 100.000.000 dam^2 = 0.0000004 dam^2

2. Mengubah are ke hektare:
   1 hektare = 100 are
   Jadi, 32 are = 32 / 100 hektare = 0.32 hektare
