225 is the answer.
11^2 = 121(actual), from this 121-112 = 9 ( digit 1 is inserted in the beginning of 121 and last digit 1 dropped to get 112).
14^2 = 196(actual), from this 196-119 = 77( digit 1 is inserted in the beginning of 196 and last digit 6 dropped to get 119).
19^2 = 361(actual), from this 361-136 = 225( digit 1 is inserted in the beginning of 361 and last digit 1 is dropped to get 136).

197

(11-2)*1+0=9
(14-2)*6+5=77
(19-2)*11+10=197
