# ∆ LMN is an equil

(1) Side of triangle = LM = a = 14 cm

Since Δ LMN is an equilateral triangle, so the area of the triangle is given by:  AT = 84.87 sq.cm

(2) Angle subtended by the corner = θ = 60°

As we know, Here , AS = 25.67 sq. cm

(3) Total area of all sector, ATS = 3× AS

ATS = 3× 25.67

ATS = 77.01 sq.cm

(4) Area of shaded region, AR = Area of triangle – Area of all three sectors

AS = AT - ATS

AS = 84.87 – 77.01

AS = 7.86 sq. cm

area of shaded region is 7.86 sq. cm
