Question

Vreau şi eu problemele: 15;13;14;11;12 sau cât puteți.

Answer 1

11)A=34800m³  Livada=A/3=34800/3=11600m³
                       Gradina=A/4=34800/4=8700m³
                      Rest=48000-(11600+8700)=27700m³
12)(L+l)(l+L)=(L+l)³=196   L+l=14cm  P=2(l+L)=2×14=28cm
13)A  ABCD=AB×CD  CD=MN  AΔBCM=BC×MN/2=200/2=100cm³   Aria hasurata=200-100=10cm³
14)A ABCD=144=l³   l=√144=12cm   =PM  PM³=MN³+PN³   MN=PN   12=2PN³  PN=√6 cm  APQMN=PN³=6cm³
