Let the breadth of the rectangle be x
Then
length= 2x+4
Perimeter of rectangle= 2(length + breadth)
=2(2x+4+x)
=2(3x+4)
=6x+8
=82
=>82=6x+8
=>6x=74
=>x=74÷6
=37/3=breadth
length=2x+4
=74/3+4
=86/3=length
Then
length= 2x+4
Perimeter of rectangle= 2(length + breadth)
=2(2x+4+x)
=2(3x+4)
=6x+8
=82
=>82=6x+8
=>6x=74
=>x=74÷6
=37/3=breadth
length=2x+4
=74/3+4
=86/3=length
