Question 680252
John’s barn is 200 yards due north of his house and his tractor is 300 yards due east of his house.
 How many yards must he walk to go directly from his tractor to his barn if he walks in a straight line?
:
This is a pythag problem; a^2 + b^2 = c^2, where
a = 200
b = 300
c = dist from tractor to barn (hypotenuse)
:
c = {{{sqrt(200^2 + 300^2)}}}
c = 360.555 yds, which is none of the above
