Find the missing number from the below options.

Fourth number = $$\left(first\ number\times third\ number\right)+\left(first\ number+third\ number\right)\times\sec ond\ number\ $$

Row 1 :

Fourth number = $$\left(3\times7\right)+\left(3+7\right)\times5$$

= $$21+10\times5$$

= $$21+50$$

= 71

Row 2 :

Fourth number = $$\left(9\times1\right)+\left(9+1\right)\times2$$

= $$9+10\times2$$

= $$9+20$$

= 29

Row 3 :

Fourth number = $$\left(6\times11\right)+\left(6+11\right)\times4\ $$

= $$66+17\times4\ $$

= $$66+68$$

= 134

Hence 134 will come in place of question mark.
