Let the sides of the triangle be 12x, 17x & 25x.
∴ 12x + 17x + 25x = 540cm ⇒ 54x = 540
⇒ x = 540/54 = 10.
∴ the sides are 12 × 10 = 120cm, 17 × 10
= 170cm & 25 × 10 = 250cm.
∴ the area of the triangle
= √270 ( 270 - 120 )( 270 - 170 )( 270 - 250)
√ 270 X 150 X 100 X 20 = 100√ 27 X 15 X 10 X 2 = 100√ 3 X 3 X 3 X 3 X 5 X 5 X 2 X 2 = 100 X 3 X 3 X 5 X 2 = 9000cm².

Lets the sides be 12x ,17x and 25x respectively.
Its perimeter = 12x + 17x + 25x which is 540cm
Therefore , according to the question
12x +17x+25x = 540
29x +25x = 540
54x = 540
X = 540/54
X = 10.
Therefore the sides are 12×10 =120
17×10= 170
25×10 = 250
Therefore area of the triangle = √S(s-a)(s-b)(s-c)
=√270(270-120)(270-170)(270-250)
=√270×150×100×20
=√3×3×3×10×3×5×10×2×2×5×5×2×10
=9000cm²
Area of the triangle is 9000cm²

Let the common ratio between the sides of the given triangle be x.
Therefore, the side of the triangle will be 12x, 17x, and 25x.
Perimeter of this triangle = 540 cm
12x + 17x + 25x = 540 cm
54x = 540 cm
x = 10 cm
Sides of the triangle will be 120 cm, 170 cm, and 250 cm.
Therefore, the area of this triangle is 9000 cm2.
