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

@ Nagendra..
can you explain it in brief...
i think you are wrong
according to the figure given above there are two right angled triangles rite?
so we have find both AC and CE by using formula (hypotys^2=side^2+side^2) and then we have to calculate AC+CE which gives AE which is required solution...

Hi this is calculated using Pythogoras theorem,
Traveled towards east = 10+2 = 12Km
Traveled towards north = 2+3 = 5 Km
We need to substitute in the formula.
= 5^2 + 12^2
= root of 25 + 144
= root of 169
= 13.
Traveled towards east = 10+2 = 12Km
Traveled towards north = 2+3 = 5 Km
We need to substitute in the formula.
= 5^2 + 12^2
= root of 25 + 144
= root of 169
= 13.

Start
Now we want to find distance from startin g point i.e start to end.
We know that pythagarus theorem,
H^2 = side^2+side^2.
Therefore,
H = sqrt(25+144).
H = sqrt169.
H = 13km.
12km comes from adding north distance and similarly 5km.

Cannot understand the solution! why are we applying Pythagoras theorem ?

I agree with @Kiran's point. Can anybody explain it more clearly?

Now which 1 method is correct, by calculating using Pythagoras or by calculating the distance in same direction?
Alfi said:

Pythagoras is the correct method.
