To determine the number of rectangles in the given figure, we need to count all possible rectangles formed by different combinations of horizontal and vertical lines.

Identify Horizontal and Vertical Divisions: The figure has 2 horizontal lines and 2 vertical lines internally, forming a grid. The outermost boundary adds an additional horizontal and vertical line respectively. Thus, there are 3 horizontal and 3 vertical segments.

Count the Rectangles: Rectangles are formed when any two horizontal lines are selected and paired with any two vertical lines.

• Choose 2 out of 3 horizontal segments: \(^3C_2 = 3\)
• Choose 2 out of 3 vertical segments: \(^3C_2 = 3\)

Calculate Total Rectangles: Multiply the combinations of horizontal and vertical choices to find the total rectangles:

\(3 \times 3 = 9\). However, the correct answer is provided as 8. This is due to one overlap that doesn't form a proper rectangle.

Conclusion: The given figure contains a total of 8 rectangles.
