Take another letter let it be 'F', and connect it to B and D making a right angled triangle AFE. You'll able to know how Pythagoras has been applied here.

If we don't get a perfect square number like the square root of 533.
Then what will be the answer, Is this 23 or none of these?

No. Here we have to find the shortest distance from a to e. so that can be find out like this..
Total distance travel towards north 2+3= 5km
Total distance travel towards east 10+2= 12km
Therefore the shortest distance will sqrt of (5*5+12*12) = sqrt(169) = 13
I think u got my point. Have a nice day.

If we assume short side be x then hypotenuse is (2x+6) and 3rd side is (2x+4).
By applying Pythagoras.
(2x+6)square = (2x+4)square + x square.
Finally, gives x square -8x-20 = 0.
Which gives x=10 and x= -2.
So, sides are 10, 24 and 26.

Can anyone explain that why we have to apply Pythagoras theorem here to get the answer?
Please explain me.
Please explain me.

Your approach is correct, but you should ask for displacement, not distance.
If you are asking for distance, then the answer will be 17.
If you are asking for distance, then the answer will be 17.
