No. If a number is irrational, it continues endlessly without a pattern. Since 2.5 stops at 5, it is rational; but if it were, say, 2.573583..., it would be irrational. Also, it can be written as the fraction 25/10, or 5/2.
At least one of the factors has to be irrational.* An irrational number times ANY number (except zero) is irrational. * The product of two irrational numbers can be either rational or irrational.

No because 25 is a rational number
No, 25 squared is not an irrational number. When you square 25, you get 625, which is a whole number and thus a rational number. Rational numbers can be expressed as the quotient of two integers, and since 625 can be expressed as ( 625/1 ), it is rational.
The square root of 25 is 5, which is a rational number.
