Question

Folositi schema de mai jos pentru a efectua transformarile :
a) 8m ^2 = ? cm ^2 = ? dam ^2
b) 250 hm^2 = ? dm^2 = ? km^2
c)174 cm^2 = ? mm^2 = ? m^2
va rog ajutati-ma...

Answer 1

8m^2 =8 *10^2*2 =8 *10^4 =8*10000=80000cm ^2
80000cm ^2 =80000 :10^2*3 =80000 :10^6 =80000 :1000000 =0.08 dam ^2
b)250 hm ^ =250 *10^2*3 =250 *10 ^6 =250000000 dm ^2
250000000dm^2=250000000:10^2*4 =250000000:10^8 =250000000:
100000000=2.5 km ^2
c)174 cm^2 =174 *10^2 =174*100 =17400 mm^2
17400mm^2 =174000: 10^2*3 =17400:10^6 =17400 :1000000 =0.0174m^2
