A rational number is one that can be represented as an integer or a fraction with an integer over an integer. An irrational number cannot be represented using integers. Examples of rational numbers: 2, 100, 1/2, 3/7, 22/7 Examples of irrational numbers: π, e, √2
Numbers are either irrational (like the square root of 2 or pi) or rational (can be stated as a fraction using whole numbers). Irrational numbers are never rational.
As the area of a rectangle is one side (length) multiples by the other (width), if either is irrational, then the area will be irrational. eg a rectangle with width 1 cm and diagonal 2 cm: using Pythagoras you can find out the length of the rectangle as √(2² - 1²) = √(4 - 1) = √3 which is irrational. The area of the rectangle is 1 cm × √3 cm = √3 cm² (which is irrational).
With great difficultly because it is an irrational number and it is about 14.69693846 by using a calculator
The square root of pi is approximately equal to 1.77245. Pi is an irrational number, meaning it cannot be expressed as a simple fraction, and its square root is also irrational. The square root of pi can be calculated using numerical methods or represented using mathematical symbols.

Assuming you mean radical functions, the answer is that you can work with problems that deal with irrational numbers. The classic one was finding the diagonal of a unit square.
A rational number is one that is the ratio of two integers, like 3/4 or 355/113. An irrational number can't be expressed as the ratio of any two integers, and examples are the square root of 2, and pi. Between any two rational numbers there is an irrational number, and between any two irrational numbers there is a rational number.
The real number system is a number system using the rational and Irrational Numbers.
The real number system is a number system using the rational and irrational numbers.
There are very many uses for them. A square, whose sides are a rational number, will have a diagonal of irrational length. The diagonals of most rectangles, with rational sides, will be irrational. The circumference and area of a circle (or ellipse) is related to pi, an irrational number. In the same way that pi is central to geometry, another irrational number, e, is fundamental to advanced calculus.
Because some decimal numbers can't be converted into fractions if they are irrational numbers.
Some problems can be, others cannot.
You cannot. The diagonal of a unit square cannot be represented by a rational number. However, because rational numbers are infinitely dense, you can get as close to an irrational number as you like even if you cannot get to it. If this approximation is adequate than you are able to represent the real world using rational numbers.
It means that either the numbers involved in the word problem are all rational or that any irrational numbers are being approximated by rational numbers.
It is algebra.
