Answer:
12m
Step-by-step explanation:
Let length and breadth the field are l and b respectively. Then,
l=2b−8⇒2b=8+l⟶(1)
The perimeter of the rectangular field =56 m
⇒2(l+b)=56m⇒2l+2b=56m
from (1), we get
2l+8+l=56⇒3l=48⇒l=16m
∴ Length of rectangular field =16m
Breadth of rectangular field =
2
16+8
=12m
