Question 936850: A rectangular field is 400 feet long and 300 feet wide. You want to walk from one corner to the
opposite corner. How many feet of walking would you save if you walk across the field instead of
walking the length and width?

Walking the length and width,
D%5B1%5D=300%2B400=700
Walking along the diagonal,
D%5B2%5D%5E2=300%5E2%2B400%5E2
D%5B2%5D=sqrt%28300%5E2%2B400%5E2%29
So the savings is,
DELTA=700-sqrt%28300%5E2%2B400%5E2%29
