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
