To find the area of the figure, we can break the shape into two parts: the triangle (Δ) and the rectangle (□). Let's go through each step:

1. **Area of the triangle (Δ):**
   - The base \( b \) of the triangle is 12 inches (the same as the base of the rectangle).
   - The height \( h \) of the triangle is 4 inches.
   - The formula for the area of a triangle is:

   \[
   A_\Delta = \frac{1}{2} \times b \times h
   \]

   Substituting the values:

   \[
   A_\Delta = \frac{1}{2} \times 12 \times 4 = 24 \, \text{in}^2
   \]

2. **Area of the rectangle (□):**
   - The width is 12 inches, and the height is 9 inches.
   - The formula for the area of a rectangle is:

   \[
   A_\Box = \text{width} \times \text{height}
   \]

   Substituting the values:

   \[
   A_\Box = 12 \times 9 = 108 \, \text{in}^2
   \]

3. **Total area of the figure:**
   - The total area is the sum of the areas of the triangle and the rectangle:

   \[
   A_{\text{total}} = A_\Delta + A_\Box = 24 + 108 = 132 \, \text{in}^2
   \]

Thus, the total area of the figure is \( 132 \, \text{in}^2 \).
