Length and circumference o f a football ground are 120 metres and 400 metres, respectively. What will be its area ?

• circumference = 2l +2b
  => 400 = 2*120 + 2b
  => b = 80 m
  
  => area = l*b = 9600 sq.m

• Answer is 9600m^2
  l=120
  p=400
  p=2(l+b)
  ==> b=80
  area=l*b
  ==>120*80=9600

• 2(120+B) = 400
  120+B = 200
  B = 400-120=80
  THEN, AREA = L x B = 120 X 80 = 9600 SQ UNITS

• 9600m^2 ans is this

• 400=2(120+b)
  b=80
  area=lb=120*80=9600

• circumference=400
  
  length=120
  
  breadth=1/2*(circumference-2*length)=1/2*(400-2*120)
  =1/2*(400-240)
  =1/2*(160)=80
  
  area of football ground=length*breadth
  =120*80=9600 m^2

• Length = 120m
  breadth = 400/2 - 120 = 80 m
  Therefore, Area= 120*80 m^2 = 9600 m^2 Ans.

• 9600
  given circumference is 400.
  length=120
  2*(l+b)=400
  2*(120+b)=400
  b=80
  area=l*b=120*80=9600.
