Question

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 length and breadth?​

Answer 1

Answer:

ans is 20. According to question breadth=P/2-breadth

Answer 2

Let the breadth be b.

Then the length will be (2b-3).

We know that the perimeter of a rectangle is of the form 2(l+b). Hence, according to the question,

2(2b-3+b)=56

2(3b-3)=56

3b-3=28

3b=31

b=31/3
