Answer» We have lengths of the sides of 1 triangular tile are a = 20 cm, b = 26 cm, c = 10cm. ∴ s = a +b +c/ 2 = 20 +26+10 /2 cm = 28 cmarea of triangle = √ 28(28-26) (28-20)(28-10)√282818√56818= 89.7cm^2area of 16 such tiles = 1689.7 Cost of polishing 1 cm2= 50 p = Re 0.50 ∴ Total cost of polishing the floral design = Rs 16 × 89.7 × 0.50 = Rs 718.3

Answer»

We have lengths of the sides of 1 triangular tile are a = 20 cm, b = 26 cm, c = 10cm.

∴ s = a +b +c/ 2 = 20 +26+10 /2 cm = 28 cmarea of triangle = √ 28(28-26) (28-20)(28-10)√28*2*8*18√56*8*18= 89.7cm^2area of 16 such tiles = 16*89.7

Cost of polishing 1 cm2= 50 p = Re 0.50

∴ Total cost of polishing the floral design = Rs 16 × 89.7 × 0.50

= Rs 718.3
