Let, breadth of the hall be b
then length of the hall = (b+4)
Perimeter = 2(b + b+4)
=> 56 = 2(2b + 4)
=> 28 = (2b+4)
=> 24 = 2b
=> 24/2 = b
=> b = 12
Length = b + 4 = 12 + 4 = 15 m
breadth = b = 12 m

- Length of the rectangle hall is 4 metres more than its breadth
- perimeter of the hall is 56 meters
- Length and breadth
Let the breadth of the hall be
- x
And let the length of the hall be
- x + 4
As we know,
Perimeter of a rectangle
Therefore,
- Breadth = 12m
- Length = (x + 4) = 12 + 4 = 16m
