Question 115557: The area of a square is 625 mm^2. Find its side length?

Remember, the area of a square is A=s%5E2 where A is the area and s is the side length of the square. So in this case A=625

625=s%5E2 Plug in A=625


sqrt%28625%29=sqrt%28s%5E2%29 Take the square root of both sides


s=25 Simplify

So the length of the side is 25 mm

Does this make sense?
