Width = 20 cm
Perimeter = 108 cm
=> 2 (Length +Width) = 108
=> Length +Width = 54
=> Length + 20 = 54
=> Length = 54 - 20
=> Length = 34 cm
Perimeter = 108 cm
=> 2 (Length +Width) = 108
=> Length +Width = 54
=> Length + 20 = 54
=> Length = 54 - 20
=> Length = 34 cm

Given
Perimeter =108cm
Breadth =20cm
Let length be l
2(l+b)=108cm
2(l+20)=108cm
2l+40=108cm
l=108-40/2
l=34cm
