Each side of a regular hexagon is 3.5cm long. The perimeter of the given polygon is
a. 17.5cm
b. 21cm
c. 18.3cm
d. 20cm

Solution:

To solve the above problem we will follow the decimal rules and we will also use the perimeter of the hexagon formula.

The side of a hexagon = 3.5 cm

Total number of sides in a Hexagon = 6

The perimeter of hexagon = sum of all six sides = 6 × 3.5 =21 cm 

Therefore, the perimeter of the given polygon is 21 cm.

✦ Try This: Each side of a regular heptagon is 6 cm long. Find the perimeter of the given polygon.

To solve the above problem you can follow the decimal rules and use the perimeter of the heptagon formula.
