The problem asks to find the shaded area of the rectangle shown in the image. Here's a step-by-step approach:

1. Total dimensions of the rectangle:

   • The height of the entire rectangle is labeled as 6 units.
   • The width of the entire rectangle is labeled as 4 units.

   So, the total area of the rectangle can be calculated as: $\text{Total Area} = 6 \times 4 = 24 \text{ square units.}$

2. Subdivision of the rectangle: The rectangle is divided into smaller parts. It consists of 6 smaller squares or rectangular sections (2 rows and 3 columns).

3. Shaded portion: The shaded portion represents 1 out of the 6 sections of the rectangle. Since the entire rectangle is divided into 6 equal parts, the area of each part is: $\text{Area of one part} = \frac{24}{6} = 4 \text{ square units.}$

Thus, the shaded area is 4 square units.

2. If the entire rectangle was divided into 12 smaller parts, what would the area of each part be?
3. What is the perimeter of the entire rectangle?
4. If the width of the rectangle were doubled, what would be the new area?
5. How can you calculate the area of a triangle if it is part of a composite shape?

Tip: Always check the total dimensions and the number of divisions when working with shaded areas to avoid confusion.
