Question
What is the perimeter of a regular octagon with 4-inch sides?
36 in
34 in
42
32 in
Hint:
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.
