Step-by-step explanation:

Perimeter of triangle = 540 cm

Ratio of sides = 25:17:12

Let common factor = x

According to question

25x + 17x + 12x = 540

54x = 540

x = 540/54

x= 10 cm

Sides

25x = 250cm

17x = 170cm

12x = 120cm

Area = √s(s-a)(s-b)(s-c)

s = perimeter of triangle/ 2

s = 540/2

s= 270 cm

Area = √270(270-250)(270-170)(270-120)

= √270×20×100×150

= √2×3×3×3×5×2×2×5×2×2×5×5×2×3×5×5

= 2×2×2×3×3×5×5×5

= 8×9×125

= 9000 cm
