Question

Un patrat are latura egala cu 5,2 dam. Aflati in m patrati , aria patratului .
Va roggg ! Multumesc !

Answer 1

P=5,2 dam=52 m P=4× l 52=4× l l=52:4 l=13 m
A= l²
A=13²
A= 169m²

Answer 2

$P_{patrat} = 5.2~dam \\ \\ L_{patrat} = 5,2~dam~:~4 \\ \\ L_{patrat} = 1,3~dam \\ \\ A_{patrat} = {1,3}^{2} \\ \\ A_{patrat} = 1,69~{dam}^{2} = 169~{m}^{2}$

Succes!
