Question

Daca am semiperimetrul unui dreptunghi 682.iar eu trebuie sa aflu latimea ce relrezinta 3/8 din lungime...cum fac

Answer 1

[tex]p= \frac{P}{2}=682 \\ l= \frac{3}{8}*L=>L= \frac{8}{3}*l \\ P=2(L+l)/:2=> \frac{P}{2}=L+l=>682= \frac{8}{3}*l+l \\ 682=l* \frac{11}{3}/:11 \\ \frac{l}{3}=62*3=>l=186 [/tex]
