It looks like the question asks to find the area of a composite shape based on the measurements provided in the image. Here's a breakdown of the shape, which is a rectangle with a smaller rectangle subtracted:

1. Larger Rectangle:

   • Height = 20 inches
   • Width = 15 inches
   • Area of larger rectangle = $20 \, \text{in} \times 15 \, \text{in} = 300 \, \text{in}^2$

2. Smaller Rectangle (subtracted):

   • Height = 9 inches
   • Width = 8 inches
   • Area of smaller rectangle = $9 \, \text{in} \times 8 \, \text{in} = 72 \, \text{in}^2$

3. Net Area:

   • Subtract the area of the smaller rectangle from the larger rectangle: $\text{Net Area} = 300 \, \text{in}^2 - 72 \, \text{in}^2 = 228 \, \text{in}^2$

The total area of the remaining part of the shape is $228 \, \text{in}^2$.

Follow-up Questions:

1. How can you break down composite shapes to calculate areas easily?
2. Why is it necessary to subtract the area of the smaller rectangle?
3. How would the area change if the smaller rectangle's dimensions were doubled?
4. What are some real-life examples where this type of area calculation is useful?
5. Could you use a similar approach to find the perimeter of this shape?

Tip:

When working with composite figures, always identify each distinct shape and calculate their areas separately before adding or subtracting as needed.
