Question

Fill in the blanks to make the statement true.

The perimeter of a rectangle becomes __________ times its original perimeter, if its length and breadth are doubled.

Answer 1

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)]
