Question

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

Answer 1

Answer:

length=16m and breadth=12m

Step-by-step explanation:

Let length be l and breadth be b

Given,

l=2b-8 -------1

Perimeter=56m

=>2(l+b)=56

=>(l+b)=28

=>(2b-8+b)=28

=>3b=36

=>b=12m

From 1,

l=24-8=16

Answer 2

Given:

• The length of a rectangular field is 8 meters less than twice is breadth.

• Perimeter of the rectangular field = 56 meters

To Find:

• Length and breadth?

Solution:

• Let breadth of Rectangle be x m
• Let Length be (2x - 8) m

Perimeter = 2(Length + Breadth)

➠ 56 m = 2(x + 2x - 8)

➠ 56 = 2(3x - 8)

➠ 56 = 6x - 16

➠ 56 + 16 = 6x

➠ 72 = 6x

➠ x = 72/6

➠ x = 12 m

Therefore,

• Breadth of Rectangle = 12 m
• Length of Rectangle = 2x - 6 = 16 m
