Among all shapes with the same area, a circle has the shortest perimeter.If the given marine reserve is a circle then area of circle is given as 58,000 square miles.

Area of any circle can be found using the formula


Area = \pi r^(2). where r is the radius of the circle.

Or 58,000 =
\pi r^(2).


r^(2)= 18471.33'

r= 135.9miles.

Perimeter is the length all around the circle= 2πr =2(3.24)(135.9)=853.51 miles.

The least length of rope one would need to rope off the perimeter is 135.9miles.
