Question

Aflati lungimea laturii patratului cu aria de a)49cm b)6.25cm c)9.61cm va rog imi trebuie urgent

Answer 1

[tex]\mathcal{A} = \ell^2 =49 \Longrightarrow \ell^2 = 7^2 \Longrightarrow \ell =7\ cm [/tex]

$\mathcal{A} = \ell^2 =6,25 \Longrightarrow \ell^2 = 2,5^2 \Longrightarrow \ell =2,5\ cm$

$\mathcal{A} = \ell^2 =9,61 \Longrightarrow \ell^2 = 3,1^2 \Longrightarrow \ell =3,1\ cm$
