To find the area of the darker shaded region in the image, we'll use the dimensions provided in the diagram. The darker shaded region is a rectangle with the following dimensions:

• Width = 8 ft
• Height = 6 ft

Step-by-step calculation:

1. Area of the larger rectangle (light shaded region):

   • The larger rectangle has dimensions of 15 ft by 8 ft.
   • Its area = $15 \times 8 = 120 \text{ square feet}$.

2. Area of the smaller rectangle (white unshaded region):

   • The smaller rectangle has dimensions of 6 ft by 4 ft.
   • Its area = $6 \times 4 = 24 \text{ square feet}$.

3. Area of the shaded region:

   • The area of the shaded region is the difference between the larger rectangle and the smaller rectangle.
   • Shaded area = $120 - 24 = 96 \text{ square feet}$.

Therefore, the area of the darker shaded region is 96 square feet.

1. How would you calculate the perimeter of the shaded region?
2. If the units were in meters instead of feet, how would that change the result?
3. How does subtracting areas differ from adding areas in composite shapes?
4. What would happen if the smaller rectangle's dimensions were different?
5. Could we solve this using a different method, such as dividing the figure into smaller shapes?

Tip: Always verify the units you're working with in geometry problems, as they can influence your final answer significantly.
