Question

9. The length of a rectangular field is 8
meters less than twice its breadth. If
the perimeter of the rectangular field is
56 meters find its the length of its sides?
?
​

Answer 1

Answer:

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

Answer 2

Step-by-step explanation:

perimeter=56

given

l=2b–8

2(l+b)=56

2[(2b–8)+b]=56

2b–8+b=28

b=12

and we have l=2b–8

l=24–8

l=16
