here you go ☆

let sides of triangle be
a=13x
b=12x
c=15x

we know that
perimeter of triangle =a+b+c

450=13x + 12x+15x

450=40x

450/40=x


x=11.25


a=146.25
b=135
c= 168.25

now we can find area using heron's formula=
$s = \frac{a + b + c}{2}$
area=
$\sqrt{s(s -a)(s - b)(s -c )}$
hope it helps you....
