If 1 inch is equal to 3 feet so you can say: 20 inches are equal to 20*3 = 60 and 19 inches is equal to 19*3 = 57 and because the school is rectangular so the area of the school is: 60* 57 = 3420 :)) i hope this is helpful have a nice day
You do a proportion so 560x300=168,000 so then you take 168,000 and divide by 800 so the answer is 210 you would have 210 British pounds for 300 dollars
