Answer:

mark as brainliest. ok.................hmmm.....

Step-by-step explanation:

Given, perimeter of a triangular field is 420 m and its sides are in the ratio 6:7:8. Let sides of a triangular field be a=6x, b=7x and c=8x. and c=8×20=160m. Hence, the area of triangular field is 2100√15m2.

Answer 2

20

Step-by-step explanation:

perimeter=420

sides=6:7:8

let =6x

7x

8x

6x+7x+8x=420

21x=420

x=420/21

x=20
