oh thank you so much gultanish
but she also solved wrong
area of triangle is not side^3
area of triangle is √s(s-a)(s-b) (s-c)
s=a+b+c/2

perimeter of the triangle =450m
let the sides are 13x, 12x, 15x
perimter of the triangle =450
13x+15x-12x=450
40x=450
x=450/40
x=45/4
first side=13*45/4= 585/4=a
second side =12*45/4= 540/4=135=b
third side=15*45/4=675/4=c
area of triangle= √s(s-a) (s-b) (s-c)
s=a+b+c/2
put the value of s in the formula you will get your answer.
