Question

the perimeter of a triangular field is 420 metre and its sides are in ratio 6 ratio 7 ratio 8 find the area of triangular field​

Answer 1

Answer:

let sides be x so,

6x + 7x + 8x = 420

21x = 420

x = 20

sides are 120 , 140 , 160

Answer 2

Step-by-step explanation:

let each side be x

ATQ

6x+7x+8x=420

21x=420

x=420/21

x=20

sides,6x=6*20

=120m

7x=7*20

=140m

8x=8*20

=160m
