Answer:
2400
Step-by-step explanation:
Perimeter of the rectangular field =2(l+b)
where l and b are the length and breadth of the rectangular field
⇒200=2(l+40)
⇒l+40=100
⇒l=60 m
Area of the rectangular field =lb
=60×40
=2400 m

Answer:
length = 70 m and breadth = 30 m
Step-by-step explanation:
Given,
length is 10 m more than twice it's breadth
Let length be l and breadth be b
l = 10 + 2b
Perimeter = 200 m
2(l+b) = 200 m
2(10+2b + b) = 200 m (substituting the value of l)
2(10 + 3b) = 200 m
20 + 6 b = 200 m
6b = 200 - 20
6b = 180 m
b = 30 m
l = 10 + 2b
l = 10 + 2*30 (substituting the value of b)
l = 10 + 60
l = 70 m
Hence,
length = 70 m and breadth = 30 m
Hope it helps..❤️
