Answer:

Jacob ran 40 yards more than Ali.

Explanation:

Football field is in the shape of a rectangle having dimensions 120 yards × 50 yards

Since Jacob runs around the perimeter of the field from one corner to other corner, therefore, distance run by Jacob =
(\text{Length+width})

Distance run by Jacob = 50 + 120 = 170 yards

Ali runs through the middle of the field diagonally on a straight line.

Therefore, distance covered by Ali =
\sqrt{\text{length}^(2)+\text{width}^(2)}

=
\sqrt{(50)^(2)+(120)^(2)}

=
√(2500+14400)

=
√(16900)

= 130 yards

Now difference between the distance covered by Jacob and Ali

= 170 - 130

= 40 yards

Therefore, Jacob ran 40 yards more than Ali.
