6cm2 , 2,5cm2 , 1dm2 , 0,007dm2 .

b) na centymetry kwadratowe :
7dm2 , 0,6dm2 , 2m2 , 0,05m2 .
____________
.. 2 - kwadratowe

Answer 1

600 mm2; 250mm2; 10000mm2; 70mm2

700cm2 60cm2 20000cm2 500cm2

Answer 2

A)
6cm2 6x6=36 cm | 1 cm = 10mm 36 x 10 = 360 mm = 60mm2
2,5 cm2 2,5 x 2,5 = 5 cm 1 cm = 10 mm 5 x 10 = 50 mm = 7,5 mm2
1 dm2 = 1 dm = 10 cm = 100 mm = 1 x 100 = 100mm = 10mm2

b)
7dm2 = 14 dm 1 dm = 10 cm | 14 x 10 = 140 cm = 70cm2
0,6 dm2 = 0,36 dm = 0,36 x 10 = 3,60 cm = 0,6 cm2
2m2 = 1m = 100 cm | 2 x 100 = 200 cm
0,05 m2 - 1m = 100 cm | 0,05 x 100 = 5 cm = 2,5cm2
