Question

the perimeter of a triangular field is 420 m and it sides are in the ratio 6:7:8 find the area of triangular field

Answer 1

Dude there is no proper details about it... So, its area can't be measured. I find the formula for this one

Answer 2

Answer:

6x + 7x + 8x = 420

21x = 420

x = 20

therefore, sides of triangle r

6x = 6*20

= 120m

7x = 7*20

= 140m

8x = 8*20

= 160m

s = 420/2

= 210

area = √s (s-a) (s-b) (s-c)

= √210 (210 - 120)(210 - 140)(210 - 160)

= √210(90)(70)(50)

= √66150000

= 8133 (approx.) m2
