Calculate the perimeter and area of an L-shaped room with given dimensions.

To find the perimeter and area of the L-shaped room, we first need to determine all the side lengths.

The given dimensions are:

• Top horizontal length: $8 \text{ m}$
• Left vertical length: $5 \text{ m}$
• Inner horizontal length (bottom part of the 'L'): $5 \text{ m}$
• Outer right vertical length: $3 \text{ m}$

Let's deduce the missing lengths:

1. The full bottom horizontal length: The total top length is $8 \text{ m}$. The inner horizontal segment is $5 \text{ m}$. Therefore, the remaining bottom horizontal segment is $8 m -
