Question

what is the perimeter of a regular decagon of side 3.6 CM​

Answer 1

Answer:

$\bold\red{36\:cm}$

Explanation:

First of all, we should know what a Regular Decagon is.

'Deca' means 10 and 'gon' is derived from 'Polygon' .

Therefore, According to this,

It is the polygon having 10 sides which are all equal in length.

Given,

Length of each side= 3.6 cm.

So, the perimeter or the sum of lengths of all sides is equal to (10 × 3.6) cm.

Hence, Perimeter = 36 cm

Answer 2

Perimeter of regular decagon = Side×10

Side = 3.6 cm

Perimeter = 3.6 × 10 = 36cm
