Placing a question mark at the end of a list of expressions or numbers does not make it a sensible question. Try to use a whole phrase (sentence) to describe what it is that you want answered.
Furthermore, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question.

m-12=25. m=37
Convert to same units then can do the calculation: 1 km = 1000 m → 3 km ÷ 25 m = (3 x 1000 m) ÷ 25 m = 3000 m ÷ 25 m = 120
Its perimeter is: 2*(10+2.5) = 25 m because its length is 25/2.5 = 10 m
25 meters.
