Question

The length of a rectangular field is one less than twice its width.Express the area in square meters.

Answer 1

Answer:

MATHS

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

ANSWER

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  =216+8=12m

Answer 2

Answer:

12m is answer.

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 =

16+8

=12m
