What is a Square Root (Page 1/10)
Square is a two dimetional concept, having length and width equal.

In Fig-1-1 both the sides are having 2 unit and therefore it is Square of 2 i.e. 2*2=4 unit
In Fig-1-2 both the sides are having 3 unit and therefore it is Square of 3 i.e. 3*3=9 unit

Now What is Square Root: This is reverse calculation to find out units in each direction
Fig 1-1 is having 4 units, and 2 unit is each direction. Therefore the Square root of 4 is 2. Similerly the square root of 9 is 3.
Now consider Fig-1-3. It is having one side 2 unit and other side 3 units i.e. total 6 uits. Now if you arrange it it any fashion, you will


not get perfect square.
To find out if square Root, lets brake two units i smaller parts. Not it is square of unit side.
Therefore the square root of 6 is 2.449 (this will be discussed in detail in future)
