Answer:Step-by-step explanation:let the sides of triangle be =12x ,17x , 25x

perimeter of the triangle = 540m

12x+17x+25x =540

54x=540

x=10m

so, the sides of the triangle are =a= 12*10 = 120m

b= 17*10 = 170m

c= 25*10 =250m

area of triangle (By herons formula) =>

s=(a+b+c)/2

=540/2

= 270 m
