Question

Ajutor ! Problema 10 repede si daca puteti 11 12

Answer 1

10.

2L/6 = 180 =>L=540 m

3l/5 = 90 =>l=150 m

540-150=390=L'

390:3=130=l'

P=2×390+2×130

P=780+260

P=1040 m

11.

l=90 m

L=124+90=214 m

P=2×90+2×214

P=180+428

P=608 m

Gard : 3×608-1=1823 m

12.

L/3 = l/2 + 84

2L=3l+504

L/3 = l + 8

L=3l+24

2(3l+24)=3l+504

6l+48=3l+504

3l=456 =>l=152 m

L=3×152+24

L=456+24 =>L=480 m
