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 answer: 235.850 m
Hope this helps.
