A) 57 cm                 

B)        54 cm

C) 60 cm  

D)        51 cm

E) None of these

Correct Answer: C

Solution :

Option (c) is correct. Here, a = 21 cm - 6 cm - (3 + 3) cm = 21 cm - 12 cm = 9 cm b = 9 cm - 6 cm = 3 cm and, c = 6 cm - 3 cm = 3 cm Therefore, the required perimeter = 21 cm + 3 cm + 3 cm + 3 cm + 3 cm + 6 cm + 3 cm + 9 cm + 9 cm = 60 cm Rest of the options is incorrect because of the correctness of option (c).
