Answer:

Step-by-step explanation:

perimeter of the rectangle =2(l+b)

30=2(10+b)

30/2=10+b

15=10+b

15-10=b

5cm=b

10cm=l

Answer :

Let the breadth be = x
Let the length = x + 10
Perimeter of rectangle = 30 cm

So according to question
Perimeter = 2(l+b)
30. =. 2 ( x+10+x )
30 = 2x + 20 + 2x
30 - 20 = 2x+2x
10 = 4x
10/4 = x
5/2 = x
So 5/2 cm = x
