The ratio of the width of a rectangle to its length equals the ratio of its length to half its perimeter.  If the area of the rectangle is 50 (sqrt(5) - 1) and the width of the rectangle is k (sqrt(5) - 1), compute the value of k.

L =Length of the rectangle.


Ratio = k*(sqrt(5) - 1) / L = L / [k*(sqrt(5) - 1) + L]


Area = 50*(sqrt(5) - 1) =k*(sqrt(5) -1) * L


Width =6.18


k = 5  and L = 10
