Va rog urgent nu trebuia neaparat toate macar jumate pls URGENTT

Answer 1

1) 1.4m+0.43dm =140cm+4.3cm =144.3 cm
2)1.4cm =14 mm
A =L*L =14*14 =196 cm^2
3)A =64 cm^2 ;  L =8cm =0.8 dm
P =4*l =4*0.8 =3.2 dm
4)A =0.5dm *75 m =5 m* 75m =375 m^2
5)2cm =0.2 dm
A unei fete =0.2*0.2 =0.04 dm^2

A totala =6*0.04 =0.24 dm^2
6)3124mm ^2 =31.24 cm^2
   0.12 dm^2 =12 cm^2
   0.07 m^2 =700 cm^2
31.24 -12+700 =719.24 cm^2
7)V =2*2*2 =8 cm =8 cl
