Area of the triangle between these points=(1/2).((√3)/2)4a^2  cm^2   It is a equilateral tringle with  ′2a′  cm each side  Angle between points=60°  So area nested by the 3 semicircles are 3(((60°)/(360°))×πa^2 )=((πa^2 )/2)cm^2   Area of the shaded region=((√3)a^2 −((πa^2 )/2))=(((2(√3)−π)/2))a^2  cm^2
