Another table, made in the same style, has its top, in the shape of an \( n \)-sided regular polygon. The length \( \mathrm{AZ}=p \mathrm{~cm} \), where Z is at the centre of the table and A is one of the corners of the table.

Beyond the Answer
The geometry of regular polygons is fascinating, especially when it comes to calculating the area or perimeter. For an \( n \)-sided regular polygon with a circumradius \( p \) (the distance from the center to a vertex), the length of each side can be determined using the formula \( \text{side length} = 2p \sin(\frac{\pi}{n}) \). This relationship helps in crafting the dimensions if you ever need to build a table or design similar structures! When considering the surface area of an \( n \)-sided polygon, one common mistake is miscalculating the total area by not accounting for the inscribed and circumscribed circles accurately. A reliable formula for the area \( A \) of a regular polygon is \( A = \frac{1}{2} \times n \times p^2 \times \sin\left(\frac{2\pi}{n}\right) \). Always double-check your angles and dimensions to ensure your calculations hold up and your creations don’t wobble!
