To find the perimeter of each L-shaped figure, we need to sum the lengths of all the sides.

First figure (on the left):

The sides are labeled as follows:

• Horizontal sides: 3, 1, and 2.
• Vertical sides: 1, 2, 1, and 1.

Thus, the perimeter is calculated as: $P = 3 + 1 + 2 + 1 + 2 + 1 + 1 = 11$ So, the perimeter of the first figure is 11 units.

Second figure (on the right):

The sides are labeled as follows:

• Horizontal sides: 1, 1, and 2.
• Vertical sides: 1, 2, 1, and 3.

Thus, the perimeter is calculated as: $P = 1 + 1 + 2 + 1 + 2 + 1 + 3 = 11$ So, the perimeter of the second figure is also 11 units.

Conclusion:

Both figures have a perimeter of 11 units.

Here are 5 related questions for further exploration:

1. How do you calculate the area of these L-shaped figures?
2. Can you find the perimeter of a similar shape with different side lengths?
3. What happens to the perimeter if one side length increases by 2 units?
4. How can we find the perimeter if the shape has diagonals?
5. Can you explain how perimeter is used in real-life applications?

Tip: The perimeter is always the total length of all the outer edges of a figure. Make sure to carefully identify each side when calculating it.
