Răspuns :
Fie 2n+1, 2n+3, 2n+5 laturile
2n+1+2n+3+2n+5=243 m
6n+9= 243 m
6n=234=> n= 39m
Laturile au lungimile: 79, 81, 83 m
2n+1+2n+3+2n+5=243 m
6n+9= 243 m
6n=234=> n= 39m
Laturile au lungimile: 79, 81, 83 m
laturile le numim:a,b,c.
a= /---/
b= /---/+2
c= /---/+2+2
egalam segmentele 243-(3x2)=243-6=237
237:3=79 --> a=79.
b= 79+2= 81
c= 81+2 = 83
Proba 79+81+83=243
a= /---/
b= /---/+2
c= /---/+2+2
egalam segmentele 243-(3x2)=243-6=237
237:3=79 --> a=79.
b= 79+2= 81
c= 81+2 = 83
Proba 79+81+83=243
