The corners of an equilateral triangle of side 10cm each are cut to form a regular hexagon. The area of the hexagon is:

• 3 regular triangle of side 10/3 cms are cut from each corner of equilateral triangle of side 10 cms.
  Area of each triangle cut from main triangle is 1/9 of original triangle.
  Area of 3 triangles cut from main triangle is 3/9 = 1/3 of original triangle.
  
  area of hexagon is (1-1/3) = 2/3 of original triangle.= (2/3)*100*(root 3)/4 = 28.867 sq cms
