As I understand the condition, you have an equilateral triangle with the side length of 1 m.

Three circles of radius 0.5 m are placed with the centers in triangle's vertices.


A strap swifts this configuration from the outside.


You need to find the length of the strap.



Then it is clear that the length of the strap is three times the side measure of the triangle PLUS three times 
the length of the 120 degs arc of the circle with the radius 0.5 m.


So, the answer is   =  meters.
