Question

calculatii laturile unui patrat egal un dreptunghi care are aria de dimensiunile de 50cm si 18cm

Answer 1

[tex]A_{dreptunghi}=L*l=\ \textgreater \ A=50*18=\ \textgreater \ A=900cm^2\\ =\ \textgreater \ A_{patrat}=l^2=\ \textgreater \ l^2=900\\ =\ \textgreater \ l= \sqrt{900} \\ =\ \textgreater \ l=30cm[/tex]
