Question

the perimeter of a triangular field is 135cm and its sides are in the ratio 25:17:12 . Find its area
plzz tell me answer guys it's urgent ​

Answer 1

Answer:

let the sides be 25x, 17x and 12x

perimeter= sum of the sides of triangle

= 54x = 135

therefore, x= 2.5

now, required sides are= 62.5, 42.5, 30

s= 135/2= 67.5

area

$\sqrt{s{s - a} {s - b}{s - c}$

Answer 2

Step-by-step explanation:

let sides be 25x, 17x , 12x,

given,

perimeter=135

then,

P=a+b+c

135=25x+ 17x + 12x,

135/54=x

X=2.5

cm

than, each sides are :

• a=25*2.5

=62.5 cm

• b=17*2.5=

42.5

cm

• c=12*2.5

=30

cm
