Three 60 degrees sectors of circles with radius 2 m MAKE one half circle piece of the radius 2 m.


So, compare the area of the equilateral triangle with the side of a= 4 m against the area of the half circle of the radius r = 2 m.


    the difference =  -  =  = 0.6648 m^2  (rounded).    ANSWER

Solved.
