100 puncte+coroana
Va tog frumos ajutatima cat se poate pana pe dat de 3.11.2017 urgent

Answer 1

ab=l/2=48/2=24
h^2=ap^2-ab^2=25^2-24^2=625-576=49 deci h=7
m^2=ap^2+ab^2=25^2+24^2=625+576=1201 deci m=radical din 1201
Alat=2*ap*l=2*25*24=1200
At=Alat+Ab=1200+48^2=3504

m^2=ap^2+ab^2 deci ab^2=m^2-ap^2=29^2-21^2=400 deci ab=20
l=ab*2=20*2=40
h^2=ap^2-ab^2=21^2-20^2=441-400=41 deci h=radical din 41
Alat=2*ap*l=2*21*40=1680
At=Alat+Ab=1200+40^2=2800
