Answer:
Given that the diameter of a semicircular protractor is 14 cm. d = 14 cm. We consider the diameter of the circle as the given shape is a semicircular protractor, i.e. the semicircle is enclosed with the line of length equal to the diameter. Therefore, the perimeter of the semicircular protractor is 36 cm.

Answer:
54 m
Step-by-step explanation:
Diameter of semi-circular plot = 21 m
Therefore, radius = 21/2 m
Thus, Perimeter = πr+2r
= 22/7*21/2 + 21
= 54 m
