Aire = hauteur x largeur
a) 6x4 = 24 dm2
24 dm2 = 2400 cm2 (il faut multiplier par 100 à chaque étape)
24 dm2 = 240000 mm2
b) 33x149 = 4917 mm2
4917mm2 = 49.17 cm2 (là il faut diviser par 100)
c) 1/2 dm2 = 0.5 dm2 = 50 cm2
50 - 49.17 = 0.83 cm2
0.83 cm2 est plus petit que 1 cm2, Matthieu a donc raison.
