suter [353]
The question is oversimplified, and pretty sloppy.

Relative to the Earth . . .
The Moon is in an elliptical orbit around us, with a period of
27.32... days, and with the Earth at one focus of the ellipse.

Relative to the Sun . . .
The Moon is in an elliptical orbit around the Sun, with a period
of 365.24... days, and with the Sun at one focus of the ellipse,
and the Moon itself makes little dimples or squiggles in its orbit
on account of the gravitational influence of the nearby Earth.

I'm sorry if that seems complicated.  You know that motion is
always relative to something, and the solar system is not simple.

Soccer fields vary in size. a large soccer field is 115 m long and 85 m wide. what are its dimensions in feet and inches? (assum
Irina18 [472]

The dimension of soccer field in ft is 377.315 ft long and 277.885 ft in width.

The dimension of soccer field in ft is 4527.78 in long and 3334.62 in in width.

As it is given that 1 m =3.281 ft

Therefore the length of the soccer field in ft is

115*3.281=377.315 ft

And width of the field is 85*3.281=277.885 ft

We know that 1 ft =12 in

Therefore the length of the soccer field in in is

377.315*12=4527.78 in

And width of the field is 277.885 *12=3334.62 in
