Hey,here is the answer to ur question......!!!!
Since it is a square and all angles =90
Therefore to
Find length of the diagonal we have to use Pythagoras theorem....!
So, (AC)^2=(AB)^2+(BC)^2
=>(AC)^2=(11)^2+(11)^2
=>(AC)^2=121+121
=>(AC)^2=242
=>AC=root242
=>AC=11root2
=>length of the diagonal =11root2
Hope this helps u....!!!!

The diagonal of a square is always sqrt (2) * the side length.

Here, the side length is 11. So:

sqrt (2) * 11 = 11 * sqrt (2)

The length of the diagonal is 11 * sqrt (2).
