Answer:
no guaranteed classification
Step-by-step explanation:
Both a rectangle and a parallelogram have two pairs of congruent sides. Because we don't know anything about the angles between these sides, it is not possible to establish which kind of figure is.
Among the given numbers, 
We have two numbers, which are 22/7 and 
Both of the numbers are irrational numbers, they are nonrepeating and nonterminating.
A fraction written in a particular way is called decimal form.
Now, evaluating both the given numbers in decimal form, we get,
22/7 = 3.14
and 
Now, Clearly, 4.12 > 3.14
Thus,
