    The total length of the border = 50.2 yards

    Step-by-step explanation:

    Step 1:

    Given,

    Diameter of the circular region = 16 yards

    We need to compute the total length of the border.

    Step 2:

    The total length of the border can be obtained by computing circumference of the region with the given diameter

    Circumference = 2 (pi) (r)

    where r is the radius

    here diameter = 16, so radius = 8 yards

    Hence circumference = 2 (3.14) 8 = 50.24 yards

    Step 3:

    Answer:

    The total length of given border = 50.2 yards (rounded off to nearest 10th)
