SPARQL Find Multiple Search Terms at Once - gis

Question

Sorry, but I have absolutely no idea what the terminology to use here is, which also makes it impossible to search for what I want to do. I only found out about SPARQL about an hour ago.
Basically, I have 475 cities that I want to know the areas of. In the course of searching various things looking for a pre-existing list (or even a very basic GIS guide) to find this, one of my results pointed out that Wikipedia has the areas for all of those cities. Unfortunately, I couldn't figure out how to get the areas for multiple cities at once.
What I can do is very, very basic. Based on the second Google Search result (I closed the other tab ages ago), I can make very basic changes to Jan Drewniak's answer. So, in principle, I can go to query.wikidata.org and find the area of each city individually by changing "Paris" in:
SELECT ?town ?area ?population ?coordinate ?country WHERE {
?town ?label "Paris"#en;
wdt:P2046 ?area;
wdt:P625 ?coordinate;
wdt:P1082 ?population;
wdt:P17 ?country.
}
And having done that, I can download the result and then change Paris again to one of the other 474 cities, download that result and so on until I've done this for all 475 cities. Then I can combine all 475 .csv files. That would work.
Obviously, I'd rather not do that. Tomorrow's Sunday, so I could but it would take ages. What I'd like to be able to do is:
run a single query that includes all 475 cities, is that possible?
get the country to report in terms that aren't wd:Q30, is that possible?
be able to tell if the results I'm getting for area are all the same unit, ideally sqkm but conversions aren't an issue, is that possible?
if it is possible to do all 475 at once, would I be able to reference the names in a .csv file?
I should also note that query.wikidata.org/ is the only place where I know to run this.
If there's some other list made by someone else of the areas of the cities in the UN's World Urbanization Prospects data of cities over 300,000 (which is where my 475 cities were culled from), then that would also work. (On a related note, Demographia has some PDF lists of Urban Areas over 1,000,000 that does have area information... if I try and copy and paste that, it just comes out as a single line, not a table. If I were to give up and find which of my 475 cities are in that list, how would I proceed?)
I've tried the following:
SELECT ?town ?area ?population ?coordinate ?country WHERE {
?town ?label "Paris"#en;
wdt:P2046 ?area;
wdt:P625 ?coordinate;
wdt:P1082 ?population;
wdt:P17 ?country.
}
SELECT ?town ?area ?population ?coordinate ?country WHERE {
?town ?label "London"#en;
wdt:P2046 ?area;
wdt:P625 ?coordinate;
wdt:P1082 ?population;
wdt:P17 ?country.
}
But query.wikidata.org gave me an error and also variations on "Paris" | "London"#en or "Paris"#en | "London"#en, by analogy to R.
As to the tags, I've just copied those from the question where I got the above code model plus added gis and SPARQL ones.
