\(\square\) ABCD has area 25
=> \(Side^2\) = 25
=> Side = 5
So, AB = BC = CD = AD = 5

Now, \(\triangle\) CDE has all angles equal => its an Equilateral Triangle
=> All sides of \(\triangle\) CDE are equal
=> CD = DE = CE = AB = BC = AD = 5

Quantity A
Perimeter of ADECB = AD + DE + EC + CB + BA = 5 + 5 + 5 + 5 = 25
=> Quantity B > Quantity A

So, Answer will be B
Hope it helps!
