- Start by understanding the shape: You have two rectangles, each measuring 10 cm by 5 cm, placed adjacent to form an L-shape.

- For the perimeter of any shape, we sum the lengths of all its outer sides.

- Arrange the rectangles in an L-shape:

- Place one rectangle horizontally (10 cm long).

- Place the other rectangle vertically upwards (10 cm long).

- The resulting shape will have six lines contributing to its perimeter:

- Two lines are 10 cm long.

- Four lines are 5 cm long.

- Thus, the perimeter is 2(10 cm) + 4(5 cm) = 20 cm + 20 cm = 40 cm.

- The correct option is 2, 40 cm.
