El área de un cuadrado es de 625cm. Averigua cuánto mide el lado y cuánto mide el perímetro del cuadrado
Rzqust [24]

Respuesta:

Largo del lado = 25cm

Perímetro = 100 cm

Explicación paso a paso:

Área de un cuadrado = L²

L es la longitud del lado del cuadrado

Dado

Área del cuadrado = 625sq. cm

625 = L²

L = √625

L = 25

Por lo tanto, el lado mide 25 cm de largo.

Perímetro del cuadrado = 4L

Perímetro del cuadrado = 4 (25)

Perímetro del cuadrado = 100cm

Por lo tanto, el perímetro del cuadrado es de 100 cm.
