Why are we using Pythagoras theorem here?

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.

When to use Pythagoras theorem and when to just add the distance. Can some one explain the difference? By simply adding the answer is 12, by the theorem it's 13.
Logically, the distance he travelled towards north will not be considered when calculating the distance covered, am I right?

Sir, here we use right angle triangle then we find individual triangles. So this is not correct I think.

The hypotenuse of a right angle triangle is 6cm more than twice the shortage side. If the third side is 2cm less than the hypotenuse. Find the sides of the triangle.
