This question is not very specific and, therefore, the answer is going to be a bit creative (hope you don't mind!).
Make a normal square with 9 coins (3 x 3) and then stack the left over coins however you like on the 9 coins! :-)

The square root of 169 is ±13. There is point in putting that back in radical form to √169, is there?
That IS the simplest radical form.
10 sqrt(13) is.
The two whole numbers closest to 162 in square root form are 12 and 13.

He has 6 2 rupee coins (Rs12) and 7 1 rupee coins (Rs7) 12 + 7 = Rs21.
The square root of 52 in radical form is 2√13. This is because 52 can be broken down into 4 and 13, and the square root of 4 is 2. Therefore, the square root of 52 can be simplified to 2√13.
2 radical 13
2*sqrt(13)
13 coins
It is: 1/13
