Question

a regular octagon (with congruent side markings) has one side labeled 5 ft. below, partial text: 15=

Explanation:

The figure is a regular octagon (all sides equal, as indicated by the marks). To find the perimeter, we multiply the length of one side by the number of sides. A regular octagon has 8 sides, and each side is 5 ft.

Step 1: Identify the number of sides and side length

Number of sides (\(n\)) = 8, Side length (\(s\)) = 5 ft.

Step 2: Calculate the perimeter (\(P\))

The formula for the perimeter of a regular polygon is \(P = n \times s\). Substituting the values, we get \(P = 8 \times 5\).

Step 3: Perform the multiplication

\(8 \times 5 = 40\).

Answer:

The perimeter of the regular octagon is 40 feet.
