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

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
