Answer:
The outside edge is 44 ft longer than the inside edge.
Step-by-step explanation:
The outside edge has a 1000 ft radius. Because the curve makes a 180° turn, the length of the curve is half of the perimeter of a circle.
Perimeter of a circle:

Outside length of the curve is given by:

R=1000 ft
Then,

Inside length of the curve is given by:
r=R-14 ft

The difference between the two lengths is:

The outside edge is 44 ft longer than the inside edge.
