Question

A diagonal de um quadrado mede 10 cm.
Calcule a medida do lado desse quadrado
d = diagonal
L = lado

$d = L \sqrt{2}$

Answer 1

d= l√2 ---> substituindo  10= l√2

                                       l=10/√2

                                       l=10*√2 / √2*√2

                                       l=5√2

                                      

resp:lado =5√2
