I want to say you that Pythagoras theorem says h^2 = p^2+b^2.
Therefore, h^2 = 10^^+2^2.
= 100+4 = root of 104+16 = 120 and this is not a perfect square.
So the answer is none of these.
Therefore, h^2 = 10^^+2^2.
= 100+4 = root of 104+16 = 120 and this is not a perfect square.
So the answer is none of these.

Try making a big right-angled triangle from the Dia.
Now the base value will be 10+2 = 12 and the height will be 2+3= 5. Now use Pythagoras theorem. 5^2+ 12^2 . Hence answer.

@Akshit.
In this problem there are two bases and to perpendiculars h^2 = (10 + 2)^2 + (2 + 3)^2.
=> h= root of 12^2 + 5^2.
=> h = root of 169.
So, h= 13.

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.

I agree with @Kiran point. Please if someone have the right conceptual clarity. Then explain the dissonance in the two thought over this questions.

Answer please.
A man faces south and walks 10 km, turn west and covers 4 km, then turn north and covers 7 km, how far is from the starting point.

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?

Extend the diagram and make it rectangle so its sides will be 12 and 5 the apply formula you will get 13 as answer.

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