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)
