dear friend
let this be the figure
|------|----|
|------|----|1
|------|----|
|--1---|-x--|
so the length of the original rectangle is 1+x and breadth is 1
so the length of the new rectangle is 1 and breadth is x]
so (1+x):1 =1:x
so solving this we get (x^2)+x+1=0
solve it by the formula to get the ans
