Answer 1

let the sides of the triangle be ,

12x cm ,16x cm and 25x cm

therefore, perimeter = (12x+17x+25x)

=54x

given,perimeter = 540 cm

therefore A.T.Q.

54x=540

or,x =540÷54

or,x=10

therefore the sides are

12x=120cm

17x=170cm

25x=250cm

we know that

heron's formula =

$\sqrt{s \times (s - a) \times (c - b) \times ( s- c)}$

therefore area=

$\sqrt{540 \times (540 - 120) \times (540 - 170) \times (540 - 250)}$

=155,998.84614957 cm^2

=155,998.85 cm^2 approx

pls follow me and mark this answer as brainliest i hope this helped u
