Question:
The perimeter of a rectangle becomes __________ times its original perimeter, if its length and breadth are doubled.
Solution:
Two times
Explanation:
We know that the perimeter of a rectangle is 2(l+b)
When the length and breadth of the perimeter are doubled, we will get
P = 2(2l +2b)
Now take 2 outside,
P = 2 [2(l+b)]
