malfutka [58]

Responder:

Escala uno

0,2 m

Los 0.067m

Explicación paso a paso:

Dado que :

Escala uno = 1: 1000

Escala dos = 1: 3000

La escala 1 tendrá una vista más detallada porque el dibujo en la escala 1 será tres rublos más grande que el dibujo producido con la escala 2. Por lo tanto, la escala más grande debería tener una vista más detallada.

Un lago de 200 m de largo en realidad:

Tamaño del lago según escala 1

1 = 1000

x = 200

Cruz multiplicar

1000x = 200

x = 200/1000

x = 0,2 m

Según escala 2:

1 = 3000

x = 200

3000x = 200

x = 200/3000

x = 0,067 m
