Length is twice its breath means b = 2l
perimeter = 228
perimeter of rectangle = 2 ( l+b)
228= 2 ( l + 2l) 
228= 2(3l)
228= 6l
l = 228/6
l= 38
b= 2(38)
b = 76
area of rectangle = lb
38 * 76 
2888 sq. units

Let the length be l
A.T.Q
length is twice its breath.then
Breath=2*length
Now,Perimeter of the rectangular field is given that 228m.Then
2(l+b)=perimeter.
2(l+2l)=228m
2(3l)=228m
6l=228m
l=228/6
l=38m
For breath, 
breath=2*length
breath=2*38
breath=76m
