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
