Answer 1

1) 0,5 ha = 0,5 x 100 = 50 are
. . 12 are = 12 x 1 = 12 are
50 + 12 = 62 are
2) 70 ha = 70 ha
2000 da = 2000 : 1000 = 2 ha
70 + 2 = 72 ha
3)*4000 m2 = 4000 : 100 = 40are
450 are = 450 are
40 + 450 = 490 are
4) 2000 m2 = 2000 : 100 = 20 are
2 hm2 = 2 x 100 = 200 are
200 + 20 = 220 are
5) 715 cm2 = 715 : 10000. = 0,0715 m2
4 dm2 = 4 : 100 = 0,04 m2
0,0715 + 0,04 = 0,1115 m2
