We have already familiar with numbers and different types of number,let us try to understand what is square and square root. As soon as we listen to square, what comes to or mind is the geometrical shape called square where all the sides are equal, now are we really going to learn about the geometrical shape square, actually not but we can try to co-relate in understanding the meaning of square number and square root with the help of a figure.

From the above figure let us try to understand the square root of a number

From the above square let us try to understand the square root of a number

As the area of a square is 9 in order to find its length it can be written as 3x3

As the area of a square is 9 in order to write it as side x side, it can be written as 3 x 3.

such that square root of 9 will be the side of the length 3.

such that square root of 9 will be the side of the length 3.
