A rectangular field 250 m long by 110 m wide. How much shorter is it to walk diagonally across the field than around the sides?

It's 1/4 the time shorter.
Use Pythagoras
h^2 = 250^2 + 110^2
= 74600
h = √74600
= 273.13 m
so what is 250+110 - 273.13 ?
h^2 = 250^2 + 110^2
= 74600
h = √74600
= 273.13 m
so what is 250+110 - 273.13 ?
