$ text{ @HV }$   + 19,41 $km^{2}$ = 19 410 000 $m^{2}$   + 22,82 $m^{2}$ = 228 200 $cm^{2}$   + 9,075 $hm^{2}$ = 90 750 $m^{2}$   + 7,34 m = 734 cm   + 3,06 dam = 306 dm   + 5,2 $dm^{2}$ = 520 $cm^{2}$   + 520 $m^{2}$ = 5,2 $dam^{2}$   + 112 $m^{2}$ 34 $cm^{2}$ = 112,00034 $m^{2}$   + 3 ha 35 $m^{2}$ = 3,00035 ha   + 2 m 34 cm = 23,4 dm
