Expert Answer:

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 =366

this is area of one triangle therefore area of 16 triangles =5766

The cost of polishing this area =50 x5766

                                                 =288006 paise

                                             =70560 paise approx  (the value of 6=2.45app)
