The area of square garden is 4/25 km^2. How long is each side?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Do you know that the area of a square is the square of its side?
The square of the length of the square, I mean?

In other words, the area = a%5E2.

Then a = sqrt%28area%29, or a = sqrt%284%2F25%29 = 2%2F5 km = 400 meters.
