<p>The<a>formula</a>for the perimeter of a heptagon is 𝑃 = 𝑎 + 𝑏 + 𝑐 + 𝑑 + 𝑒 + 𝑓 + 𝑔, where a, b, c, d, e, f, and g are the sides of the heptagon.</p>

7
<p>For instance, if a heptagon has sides a = 4, b = 5, c = 6, d = 7, e = 8, f = 9, and g = 10, then its perimeter is p = 4 + 5 + 6 + 7 + 8 + 9 + 10 = 49.</p>
