Side of equilateral riangle = 28 cm

Radius of each circle = 14 cm

Area of the Equilateral triangle :

Area = (√3/4)*a²

Here a is side of triangle

Area= (√3/4)*28²

Here √3 = 1.732

Area =(1.732/4)*28*28=339.472 cm²

Area covered by three circular sectors:-

Each circle covers a 60° sector.

Area of one sector= 1/6*22/7*14*14=102.67 cm²

So total area of three sectors = 102.67*3=308 cm²

The area of triangle not included in circle = Area of triangle - Area covered by circular sectors

= 339.48-308=31.08 cm²

Option (c) is the correct answer.
