Best answer

Consider a = 16cm, b = 12cm and c = 20cm

So we get

So the area of one tile = 96cm2

The area of 16 triangular tiles = 96 (16) = 1536 cm2

It is given that the cost of polishing the tiles per sq cm = ₹1

So the cost of polishing all the tiles = ₹ (1 × 1536) = ₹ 1536

Therefore, the cost of polishing the tiles is ₹ 1536.
