Answer:

A) Rational.

Explanation:

We have been given a real number
√(1.21). We are asked to determine whether our given number is rational or irrational.

We know that an irrational number is a number that cannot be written as fraction.

Upon evaluating our given number, we will get:


√(1.21)=1.1

We can write 1.1 as fraction as shown below:


1.1=(11)/(10)

Since we can write our given number a fraction, therefore, our given number is a rational number and option A is the correct choice.
