Aria este 121 deci ii aflam radicalul, obtinem 11. Dupa aceaa inmultim 11x4 si dobtinem 44. R:44
[tex] A_{patrat} = L^{2} =121 cm^{2} [/tex]
[tex] L_{patrat} = \sqrt{121} =11 cm [/tex]
[tex] P_{patrat} =4L=4*11=44cm[/tex]
[tex] L_{patrat} = \sqrt{121} =11 cm [/tex]
[tex] P_{patrat} =4L=4*11=44cm[/tex]
