Answer:
Let breadth of the rectangle be x cm,
So, length will be (x + 2 ) cm
We know that ,
Perimeter = 2 ( l + b )
24 = 2 ( x + 2 + x )
x+2 + x = 12
2x + 2 = 12
2x = 12 - 2
2x= 10
x = 5
So, breadth = 5cm
length = 7 cm

Step-by-step explanation:
perimeter=24cm
l=2+b
p=2(l+b)
24=2(2+b+b)
24=2(2+2b)
24=4+4b
4+4b=24
4b=24-4
4b=20
b=20/4=5
l=2+5=7
hence length=7cm and breadth=5cm
