Question

The side length of a regular decagon is 13m, then the perimeter of a regular decagon?

Answer 1

decagon has 10 sides
one side length = 13m
perimeter of decagon = 13× 10 = 130m

Answer 2

Heya !!!

Given :-

Regular Decagon whose one side is 13 cm.

We know that Decagon has 10 sides.

As it is regular, so all sides will be of same length, i.e. 13cm.

So, perimeter of the given regular Decagon
= 10 × Side

= 10 × 13
= 130 cm.

Hence, the perimeter of given Decagon is 130 cm.

Hope it helps
