A square region has an area of b square inches and a perimeter of n inches. If \(n=\frac{b}{3}\) what is the length, in inches, of the side of the square?
A. 12
B. \(12 \sqrt{2}\)
C. 48
D. \(48 \sqrt{3}\)
E. 144
Kudos for the right answer and explanation

Let side of square be 's'
so area is S^2 = B (square inches)
4s = n
and n = B/3
so 4s = s^2/3 [subsituting]
s = 12
Hence A.
the trick is to realize B is a unit not a B^2 [I found this tricky! and kept getting b removed the equation]
