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 = 22÷(16+8)
=12m

Answer:
length= 16m breadth= 12m
Step-by-step explanation:
Let the Breadth of the rectangular field be x.
length of the field= 2x-8 (according to question)
perimeter of rectangle= 2l+2b= 56m
so, 56= 2(2x-8)+2x
56= 4x-16+2x
56= 6x-16
x = 12m
- breadth of the rectangular field= 12m
- length of the rectangular field= 2*12-8= 16m
