Math Problem Statement

Determine the perimeter of a regular polygon whose one side measures 24 cm and each central angle is 24 degrees.

Solution

To determine the perimeter of the regular polygon, we can follow these steps:

Step 1: Determine the number of sides of the polygon

The central angle of a regular polygon is related to the number of sides by the formula:

Central Angle=360n\text{Central Angle} = \frac{360^\circ}{n}

where nn is the number of sides of the polygon. We are given that the central angle is 24 degrees, so:

24=360n24^\circ = \frac{360^\circ}{n}

Solving for nn:

n=36024=15n = \frac{360^\circ}{24^\circ} = 15

So, the polygon has 15 sides.

Step 2: Calculate the perimeter

The perimeter PP of a regular polygon is given by the product of the number of sides and the length of one side:

P=n×side lengthP = n \times \text{side length}

Here, n=15n = 15 and the side length is 24 cm. Thus:

P=15×24=360cmP = 15 \times 24 = 360 \, \text{cm}

Final Answer:

The perimeter of the regular polygon is 360360 cm.
