Explicație pas cu pas:
[tex]A_{dreptunghi}=L\cdot l, unde\:L\:reprezint\breve{a}\:lungimea,\:iar\:l\:reprezint\breve{a}\:l\breve{a}timea.\\ \implies 100\:m\cdot l=2500\:{m}^{2}\implies l=\frac{2500\:{m}^{2}}{100\:m}\implies \boxed{\bold{l=25\:m}}[/tex]
[tex]A_{p\breve{a}trat}={l}^{2},\:unde\:l\:reprezint\breve{a}\:latura\:p\breve{a}tratului.\\ \implies {l}^{2}=2500\:{m}^{2} \implies l=\sqrt{2500\:{m}^{2}} \implies \boxed{\bold{l=50\:m}}[/tex]
