Answer 2

Answer: 9000cm2

Step-by-step explanation: Let common factor = x

sides = 12x , 17x , 25x

Perimeter of triangle = 540 cm  

12x + 17x + 25x = 540

54x = 540

x = 10

now ,

12x = 120cm

17x = 170cm

25x = 250 cm

s = 540/2

s = 270 cm

area = √s(s-a)(s-b)(s-c)

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

area = √ 270 × 150 × 100 × 20

area =  9000 cm2
