Answer:

187.44cm2

Step-by-step explanation:

Given,

Radius = 7cm

Side of equilateral triangle = 14cm

Area of circle =

Area of circle =  

Area of equilateral triangle =  

Area of equilateral triangle =  

=  

We know that an equilateral triangle always subtend an angle of 60 at centre area of sector =  

=

= = 25.666cm2

This area is common in both the figure so,

Area of shaded region = (area of circle + area of equilateral triangle - 2×area of sector)

= (154+84.77-2×25.67)

= (238.77-51.33) = 187.44cm2
