Question 758158
Pythagorean question.
Consider a right angled triangle:
Upright side = 120 metres
Base side = 90 metres
The diagonal path is the hypotenuse
 120^2 + 90^2 = hypotenuse^2
 14400 + 8100 = hypotenuse^2
 Hypotenuse^2 = 22500
 Hypotenuse = square root of 22500
 Hypotenuse = 150 metres
This is the length of the pathway.
Hope this helps.
