please answer fast . please tell correct​

Answer 1

Answer:

ratio =3:4:5=3x+4x+5x=12x

12x=108

X=108/12

X=9

3x=3×9=27

4x=4×9=36

5x=5×9=45

area of the triangle formula =1/2×b×h

height of the triangle=?

pythogaros triplet =acsquare=absquare+bcsquare

= 27square =18square+bcsquare

height=20

1/2×36×20=360

hence,

the area of the triangle is 360
