Question

Copletati cu numere care lipsesc: a) 1km patrat = m patrati = dm patrati b) km patrati = 1m patrati = dm patrati

Answer 1

Km, hm, dam, m, dm, cm, mm

$a)~1~km^{2}=?~m^{2}$
$1~km^{2}=3~salturi~spre~dreapta,~dar~este~la~puterea~2,~deci~\cdot2}=100000~m^{2}$

$100000~m^{2}=?dm^{2}$
$100000~m^{2}={1~salt~spre~dreapta,~dar~este~la~puterea~2,~deci~\cdot2}=10000000~dm^{2}$

$~~ \\ ~~$

$b)~1~m^{2}=?~km^{2}$
$1~m^{2}={3~salturi~spre~stanga,~dar~este~la~puterea~2,~deci~\cdot2}=0,000001~km^{2}$

$1~m^{2}=?~dm^{2}$
$1~m^{2}={1~salt~spre~dreapta,~dar~este~la~puterea~2,~deci~\cdot2}=100~dm^{2}$
