#) Trả lời :
a) 5 cm2 = 500 mm2 ; 12km2 = 1200 hm2
1 hm2 = 10 000 m2 ; 7hm2 = 70 000 m2
1 m2 = 10 000 cm2 ; 5 m2 = 50 000 cm2
12 m2 9 dm2 = 1209 dm2 ; 37 dam2 224 m2 = 3924 m2
b) 800 mm2 = 8 cm2 ; 3400 dm2 = 34 m2
12 000 hm2 = 120 km2 ; 150 cm2 = 1 dm2 50 cm2
90 000 m2 = 9 hm2 ; 2010 m2 = 20 dam2 20 m2
#~Will~be~Pens~#
9 m2 15 dm2 = 9,15 m2
21 m2 8 dm2 = 21,08 m2
73 dm2 = 0,73 m2
7 m2 25 m2 = 32 m2
105 m2 7 dm2 = 105,07 m2
45 cm2 = 0,0045 m2
mih ghi sai câu đầu . 25m2 25dm2 nha
\(15dm^29cm^2=1509cm^2\)
\(10dm^26mm^2=100006mm^2\)
