Draw the picture:
From the point where he begins to cross the field
draw a line parallel to the 80 ft base.
----
You have a right triangle with legs = 80 and 60
Find the hypotenuse of that triangle:
Ans: diag = sqrt[80^2+60^2] = 100 ft.

This problem can be solved as a right right triangle with legs of 60 ft and 80 ft with the diagonal
as the hypotenuse. Note, also, this is a (3-4-5) right triangle so, the hypotenuse or diagonal =100ft
