He walks 200m west and 125m north how far away is he from his starting point

If you draw a horizontal line then vertical line and then connect starting point to final point then you would get a right triangle.

So for this triangle, base is 200 m and height is 125 m. Our goal is to find the length of hypotenuse. We can use Pythagorean theorem.

(200)² + (125)² = c²

√( (200)² + (125)² ) = c

√( 55625 ) = c

235.850 ≈ c

Final 235.850 m

Hope this helps.

The correct answer is c
