HYY XDStep-by-step explanation:

Perimeter=135cm

Let the ratio be. 25x,17x,12x

25x+17x+12x=135

54x=135

x=135/54

x=2.5

Putting the value 12x=12×2.5=30

17x=17×2.5=42.5

25x=25×2.5=62.5

Sides of triangle are 30 cm,42.5cm,62.5cm

Area of triangle=1/2bh

=1/2×62.5×42.5

=2656.25/2

=1328.125

Step-by-step explanation: let the ratio be 25x, 17x , 12x,

given,p=135

then,

P=a+b+c

135=25x+ 17x + 12x,

135/54=x

X=2.5

than, each sides are =a=25*2.5=62.5 cm

b=17*2.5=42.5

c=12*2.5=30
