Question

What is the perimeter of a regular octagon with 4-inch sides?

  1. 36 in    
  2. 34 in    
  3. 42    
  4. 32 in    

hintHint:

Polygon is a two- dimensional closed figure which is made up of three or more line segments. Each polygon has its own properties based on the number of sides. Perimeter of a regular polygon can be determined using the formula Perimeter of the polygon= Length of one side of the polygon x No. of sides . Here, we have to find the perimeter of the given polygon.

The correct answer is: 32 in


    In the question it is given that
    Length of one side= 4
    No. of sides= 8
    Here, we have to find the perimeter of the given polygon.
    Perimeter of the given polygon = length of one side× no of sides
    = 4×8
    = 32 inches
    So, the perimeter of the given polygon is 32 inches.
    Therefore, the correct option is d, i.e., 32 inches.
