The length around it is

       (two lengths of the rectangle) + (2 halves of the circle)

   =        (182 meters)                + (the circumference of one full circle)

The circumference of a circle is    (pi) x (diameter).

Notice that the width of the rectangle is also the diameter of the circle.
