    21 m

    Step-by-step explanation:

    Circumference of circular park = 2πr

    65 = 2πr

    Solve this to find r:

    65 = 2 x 3.14 x r

    r = 65 / 6.28

    r = 10.35

    Now to find the find the distance of the new sidewalk, multiply r with 2 (to get the diameter):

    2 x 10.35 = 20.7 ≈ 21 m

    Therefore, the distance of new side walk, rounded to the nearest meter, is 21 m.
