1 Answer

Answer :

Measures of the sides of the triangular tile are 28 cm, 9 cm and 35 cm.  Let a = 28 cm, b = 9 cm, c = 35 cm Semi-perimeter,  s = (a + b + c)/2   = (28 + 9 + 35)/2  = 36 cm ∴   Area of one triangular tile = under root( √s(s -a)(s -b)(s - c))  = under root( √36(36 – 28)(36 - 9)(36 – 35)) =  under root( √36 x 8 x 27 x 1) = 36 √6 cm2  So, area of 16 triangular tiles = 16 x 36 √6 cm2   = 576 √6 cm2 = 576 x 2.45 = 1411.2 cm2 Hence, cost of polishing the tiles at the rate of ₹ 1/2 per cm2  =  ₹ 1/2 x 1411.2 = ₹ 705.60
