let rhombus long diagonal is M , short diagonal is N and side is a

now according to question
area of rhombus =1/2area of square which side is also side of rhombus
=>1/2M x N=1/2 (a^2+a^2+a^2+a^2)=2a^2
=>M x N=4a^2-------(1)
but we know rhombus side and diagonal relation
M^2+N^2=4a^2----------(2)
compare (1) and (2)
M^2+N^2=MN
divided both side by MN and arranged we find
(M/N)^2-(M/N)+1=0
here we see
(M/N) ratio is always complex
i.e M/N=(1+iroot3)/2



abhi178: hey friend here ratio is in complex number find
abhi178: tell me here answer rational or complex
Rajan22: I also found it in complex no.
