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
