You can divide the figure like this, and shift the areas. You will end up with a rectangle that is 25m by 2m. (I've only shown the divisions for 1 side, you can try the dividing other side on your own.
The area not covered by path
= area of whole rectangle - area of the shaded rectangle formed
= 11m x 25m - 2m x 25m
= 275m² - 50m²
= 225m²
