To calculate the perimeter of the shapes based on the given sequence of numbers, we first need to understand how these numbers might represent the sides of a polygon. It appears you have given a sequence of side lengths.

Let's assume this sequence represents a closed shape where these lengths are consecutive sides. The given numbers are: 1, 3, 1, 1, 2, 1, 2, 1.

Step 1: Calculate the Perimeter

To find the perimeter of a polygon, sum the lengths of all its sides.

Perimeter \( P \) = \( 1 + 3 + 1 + 1 + 2 + 1 + 2 + 1 \)

Calculating this step-by-step:

  • \( 1 + 3 = 4 \)
  • \( 4 + 1 = 5 \)
  • \( 5 + 1 = 6 \)
  • \( 6 + 2 = 8 \)
  • \( 8 + 1 = 9 \)
  • \( 9 + 2 = 11 \)
  • \( 11 + 1 = 12 \)

Thus, the perimeter is:

Perimeter = 12 units

Step 2: Calculate the Area

To determine the area, we need more information about the shape of the figure (e.g., is it a rectangle, triangle, irregular shape, etc.?). The values provided may not directly correlate to a standard geometric shape without a diagram or additional context.

If you know the shape (for example, if it were a polygon with a specific formula for area), please provide that information, or if possible, provide a diagram or further description of the shape.

For general purposes, many polygons have specific area formulas, and without that information, we cannot assume a specific area. If you can clarify the shape, I can help you find the area as well.

For now:

Area = ? square units (needs shape clarification)
