Answer:    105.19 \text{ square cm}      

Step-by-step explanation:

Since, by the SAS formula of finding the area of triangle,

The area of triangle, A = \frac{1}{2}\times s_1\times s_2\times sin\theta

Where, s_1 and  s_2 are adjacent sides and \theta  is the included angle of these sides

Here, s_1=22 s_2=10

And, \theta=107^{\circ}

Thus, the area of the triangle ABC,

A = \frac{1}{2}\times 22\times 10\times sin (107)^{\circ}

A = 110\times 0.95630475596

A = 105.193523156\approx 105.19\text { square cm}

Therefore, Third Option is correct.
