Va rog frumos, urgent, plssss​

Answer 1

4. 24 km= 24000m      

3200 mm= 320 cm

140 m= 1400 dm

2540 dm= 25400 cm

17 hm= 17000 dm

50000 mm= 5 dam

500 m= 5 cm= 0,5 km

7 km= 700 dam= 70 hm

6320 hm= 632 dam= 63,2 m

95000 cm= 950 m= 950000 mm

5. 7 km 555 m= 7000+555=7555 m

81 hm 223 m= 8100+223= 8323 m

45 km 141 dam= 45000+1410=46410 m

160 cm 12 m= 16+120=136 dm

6.5420+214=5634 hm

253-120=133 dm

3100m= 31 hm

6523-1250=5273 cm

10000 dam= 100 km

80+60=140 m

7. Lungimea unei camere in forma de dreptunghi este egala cu 5 m

latimea este egala cu 2 m.

P dreptunghi= 2*( L+l ) 2*7=14m

A dreptunghi= L*l= 2*5=10 $m^{2}$
