    Given Shape: As we see figure above, we can say that 5 and 14 will act as diameter for semi circles.

    Perimeter = length of boundary 

    Perimeter = length of two semi circles with diameter , d1 = 5 + length of two semi circles with diameter d2 = 14

    2 x (1/2 x 2pi(d1/2)) + 2 x (1/2 x 2pi(d2/2))=

    pid1 + pid2

    pi(d1 + d2)

    pi(5 + 14)

    19pi = 59.690 units = 60 rounded to integer

    Perimeter of shape = 59.70 units

    I Hope this helps!
