Answer 1

Answer:

let side of triangle is X.

So, 1st side 13x (a)

2nd side 12x (b)

3ed side 5x (c)

Now,

perimeter of a triangle is

a+b+c= 450

NOW PUT THE VALUE

you will get X and then multiple value of X by 13 , 12 and 5.

then

area of triangle = h×b/2

h= hieght put any one for example 13X

b = base pit it 5X

hence u get ans.
