Question

El lado de un cuadrado mide 5√2 ¿Cuánto mide su diagonal?

Answer 1

Respuesta:

d = 9.99

Explicación paso a paso:

${d}^{2} = {l}^{2} + {l}^{2}$

$l = 5 \sqrt{2} \\ l = 5(1.4142) \\ l = 7.071 \\ {d}^{2} = {l}^{2} + {l}^{2} \\ {d}^{2} = {7.071}^{2} + {7.071}^{2} \\ {d}^{2} = 49.999 + 49.999 {d}^{2} = 99.998$

$d = \sqrt{99.998} \\ d = 9.99$
