Perimeter of a Regular Heptagon

Consider a regular heptagon, which is a seven-sided polygon where all sides and angles are equal. If the length of each side of the regular heptagon is 4 units, calculate the perimeter of the heptagon.

The perimeter of a polygon can be calculated using the formula:

$$ ext{Perimeter} = n imes s $$

where n is the number of sides and s is the length of one side.
