| Since we know that the area of a 24-gon is 8n sq. units, and the area of the circle inscribed in it is 2p sq. units.
We can split a quadrilateral into 24 triangles.
Let’s write the area of 24 gons as:
S24 = 24 * S triangle = 8п;
Hence S of the triangle = 8n / 24 = n / 3 = 1/2 * a24 * r.
a24 = 2п / 3r.
The area of the inscribed circle is S = nr ^ 2 = 2п;
r ^ 2 = 2;
r = √2.
It remains to find the perimeter of the 24 – x gon:
P24 = 24 * a24 = 24 * 2п / 3r = 16п / √2 = 8√2 * п.
Answer: P24 = 8√2 * п.
