consider the breadth of the field = b m
thence length(l) = (b+26) m
distance around the field = 2(l+b) =400 m
⇒ 2(b+26+b) = 400
⇒ 2b+26 = 200
⇒ b = 87 m ,then l = b+26 = 113
hence length & breadth of rectangular field are 113 & 87 respectively.

Answer:
`perimeter = 56m
by the question,
breadth= x
∴length= 2x-8
perimeter= 2(l+b)
56=2( 2x-8+x)
56=4x-16+2x (distributive property)
56=6x-16
56+16=6x
72=6x
x=12
breadth=12
length=2x-8
=16
