Aşağıdakı fiqurun sahəsini hesablayın.

A) $192 \text{ sm}^2$

B) $153 \text{ sm}^2$

C) $132 \text{ sm}^2$

D) $69 \text{ sm}^2$

This question includes visual content: The image shows an L-shaped rectilinear figure with a staircase-like inner boundary. The outer vertical left side is labeled 12 sm. The bottom horizontal side is labeled 6 sm. Moving up from the bottom-left corner, there is a vertical segment of 12 sm, then a top horizontal segment of 16 sm. The right side descends in three steps: a vertical segment of 4 sm, a horizontal segment of 5 sm going left, a vertical segment of 4 sm, another horizontal segment of 5 sm going left, and a final vertical segment of 4 sm meeting the bottom segment of 6 sm. All angles appear to be 90 degrees.
