Let the length be x and the breath is x -5 .
Therefore 2x+2(x-5)= 30
2x+2x-10=30
4x-10=30
4x=30+10
X= 40/4=10.
Therefore the length is 10 and breadth is x-5, 10-5=5.
Therefore 2x+2(x-5)= 30
2x+2x-10=30
4x-10=30
4x=30+10
X= 40/4=10.
Therefore the length is 10 and breadth is x-5, 10-5=5.

length be x breath=x-5
p=2 (x+x-5) =30
2x-5=15
x=10
p=2 (x+x-5) =30
2x-5=15
x=10
