It is a rational number because it is a terminating decimal number which can also be expressed as a fraction
The area of a triangle can be a rational number or an irrational number depending on its dimensions.

Such a product is always irrational - unless the rational number happens to be zero.
The sum of a rational and irrational number must be an irrational number.
rational * irrational = irrational.
Any, and every, irrational number will do.
Let R1 = rational number Let X = irrational number Assume R1 + X = (some rational number) We add -R1 to both sides, and we get: -R1 + x = (some irrational number) + (-R1), thus X = (SIR) + (-R1), which implies that X, an irrational number, is the sum of two rational numbers, which is a contradiction. Thus, the sum of a rational number and an irrational number is always irrational. (Proof by contradiction)
The area of a triangle can be a rational number or an irrational number depending on its dimensions.

It is a rational number.
It is irrational. 133 = 7*17 and so is not the square of any rational number. Therefore its square root cannot be rational.
Irrational.
it is a rational number but 4.121314..... is an irrational no
Such a product is always irrational - unless the rational number happens to be zero.
The product of a rational and irrational number can be rational if the rational is 0. Otherwise it is always irrational.
No number is irrational and rational.
If an irrational number is added to, (or multiplied by) a rational number, the result will always be an irrational number.
