Answer:
100,308m
Step-by-step explanation:
Running corner to corner in a rectangle would create a right triangle.
The player's path would be the hypotenuse of the triangle, which can be found using pythagorean theorem, a²+b²=c².
6464²+100100²=c²
41,738,296 + 10,020,101,000 = c²
10,061,748,296 = c²
c=√10,061,748,296
c=100,308m
