Răspuns :
a) latura =√324=18
P=4a=4*18=72
b) P dreptunghiului=2(1300+200)=3000m
A dreptunghiului=1300*200=260000m²
P=4a=4*18=72
b) P dreptunghiului=2(1300+200)=3000m
A dreptunghiului=1300*200=260000m²
Apatratului=l²=>324=l²=>l=18
Ppatrat=4l=>P=72m
Pdreptunghi=2(L+l)=2(1300+200)=>P=3000m
A dreptunghi=L*l=1300*200=260 000 m²
Ppatrat=4l=>P=72m
Pdreptunghi=2(L+l)=2(1300+200)=>P=3000m
A dreptunghi=L*l=1300*200=260 000 m²
