this is a map of the mars exploration rover opportunity predicted landing site on mars. the scale is 1cm : 9.4km. What are the approximate measures of the actual length and width of the ellipse?
I mostly need to know how to set it up :)

Respuesta :

Answer: The actual length and actual width of the ellipse are 2.12 cm and 2.65 cm.

Step-by-step explanation:

Since we have given that

The scale of mars is

[tex]1\ cm:9.4\ km[/tex]

since we know that the dimension of ellipse is

[tex]20\ km\ by\ 25\ km[/tex]

so, According to scale,

[tex]1\ cm=9.4\ km\\\\1\ km=\frac{1}{9.4}\ cm\\\\20\ km=\frac{20}{9.4}\ cm\\\\20\ km=2.12\ cm[/tex]

Similarly,

[tex]1\ cm=9.4\ km\\\\1\ km=\frac{1}{9.4}\ cm\\\\25\ km=\frac{25}{9.4}\ cm\\\\25\ km=2.65\ cm[/tex]

Hence, the actual length and actual width of the ellipse are 2.12 cm and 2.65 cm.
