Step-by-step explanation:

side of the triangle ABC=10cm

Area of the equilateral triangle =(√3/4×10×10)

=25√3

Length of radius of each sector =5cm

Area of each sector=(60°/360°×22/7×5×5)

=275/21 cm²

area of 3sector =275/21×3

=275/7

Area of the shaded region=(25√3-25/7) cm² [25√3=43.3] = (43.3-39.28) =4.03 cm²(approx)
