Perimeter from regular polygon properties
publish date: 2026/05/16 21:27:31.071969 UTC
A regular polygon has a total calculated area of \(240\text{ cm}^2\) and an internal apothem length of \(8\text{ cm}\). Calculate its full perimeter boundary path line length.
Answer = (1)
Correct Answer
(1) 60
Explanation
Isolate \(P\) from \(A = \frac{1}{2}aP\):
\[240 = \frac{1}{2} \times 8 \times P \implies 240 = 4P \implies P = 60\text{ cm}\]
