Perimeter of Regular Pentagon Calculator

Need to calculate the perimeter of a regular pentagon quickly and accurately? Our Perimeter of Regular Pentagon Calculator makes it easy to find the total length of all sides of a pentagon in seconds. Whether you’re a student working on geometry homework, a teacher preparing lessons, or an engineer applying geometric calculations, this tool ensures fast, reliable, and error-free results every time.

📏 Understanding a Regular Pentagon

A pentagon is a polygon with five sides.
A regular pentagon has five equal sides and five equal angles (each angle = 108°).
The perimeter of a pentagon is the sum of the lengths of all its sides.
👉 For a regular pentagon, since all sides are equal, calculating the perimeter becomes very simple.

⚖️ Formula for the Perimeter of a Regular Pentagon

P = 5 × a

Where:
P = Perimeter of the pentagon
a = Length of one side
👉 This means you only need the length of one side to calculate the entire perimeter.

📚 Examples of Perimeter of a Regular Pentagon

Side length = 4 cm

P = 5 × 4 = 20 cm

✅ So, the perimeter = 20 cm

Side length = 10 m

P = 5 × 10 = 50 m

✅ So, the perimeter = 50 m

Side length = 7.5 mm

P = 5 × 7.5 = 37.5 mm

✅ So, the perimeter = 37.5 mm

Side length = 12 inches

P = 5 × 12 = 60 inches

✅ So, the perimeter = 60 inches

Side length = 2.3 km

P = 5 × 2.3 = 11.5 km

✅ So, the perimeter = 11.5 km
