The area of a square = side squared. So, the length of a side would be the square root of the expression that you have. (4x+y)^2 equals 16x^2+8xy+y^2....so the length of the side is (4x+y). To get an actual numerical answer you would need values for x and y.

Factor it out
16x^2+8xy+y^2 = (4x+y)(4x+y) or (4x+y)^2
The square root is 4x + y

|4x+y| is the right answer. When you take the square root of something squared you need to include the absoulte value.
