(i) It is an order and therefore, it is not a statement.
(ii) From the context it is not clear which room is referred here and also the term rich is not well defined.
So, the given sentence is not a statement.
(iii) This sentence is always true and therefore, it is a statement.
(iv) For those who like mathematics it may be a fun but for others it may not be.
So, the given sentence cannot be judged to be true or false.
Hence, it is not a statement.
(v) It is not known who she is. So, the given sentence is not a statement.
(vi) Clearly, `sqrt(2)` is an irrational number. So, the given sentence is false. Therefore, it is a statement.
(vii) Clearly, the given sentence is always true.
Hence, it is a statement.
(viii) All the sides of a square as well as that of a rhombus are equal. But, the sides of a trapezium as well as that of a rectangle are inequal.
So, the given sentence is sometimes true and sometimes false. Hence, it is not a statement.
