since the tile is triangular, the area of of the triangle with sides 9,28,35 can be obtained by heros formula
A =s(s-a)(s-b)(s-c) where s=a+b+c/2
A =36(27)(8)(1)
A =9x4x6
A =36 this is area of one triangle therefore area of 16 triangles =576 The cost of polishing this area =50 x576 =28800 =70560 paise approx (the value of 6 sq.cm
