Please answer my question​

Answer 1

Step-by-step explanation:

let the sides be 12x , 17x, 25x

the perimeter of traingle is the sum of all the sides.

hence, 12x+17x+25x=540

=> 54x=540

=> x=540/54

=> x=10

So the sides are 12*10=120cm

17*10=170cm

25*10=250cm

using heron's formula we get

semi perimeter=(120+170+250)/2

=270

Now √(270-120)+(270-170)+(270-250)

√(150+100+20)

√270

so,the area of triangle is √270cm²
