A)  85 cm                       

B)  88 cm                 

C)                                             72 cm             

D)         82 cm

Correct Answer: D

Solution :

We have, AD = BF + FE + EC \[=4+9+5=18\]cm Also, AB = DC = 7 cm FG = EH = 9 cm Now, perimeter of the given figure = AB + BF + FG + GI + IH + HE + EC + CD + DA \[=7+4+9+15+8+9+5+7+18=82\]cm
