Question

perimetrul unui teren de forma dreprthunghiulara este de 66m impartind lungimeala latime se obtine 5 si restul3

Answer 1

P=2(L+l)
L:l=5r3=>L=5l+3
66=2(5l+3+l)
66:2-3=6l
30=6l=>l=30:6=>l=5 m
L=5x5+3=>L=28 m

Answer 2

2L+2l=66 m. L=|-|-|-|-|-|+3|. L=|-|-|-|-|-|+3|. l=|-|. l=|-|. 66m-3-3=60. 60:12=5 (l). 5×5+3=28. Verificare: 2L+2l=2×28+2×5= 56+10=66.
