Question

if the side ofa parallelogram are incread to twice its original shape
​

Answer 1

Answer:

Let l be the length and b be the breadth of the parallelogram.

Then, perimeter =2(1+b)

If both sides of the parallelogram are doubled, then the breadth and length become 2l and 2b, respectively. Now, perimeter =2(2l+2b)=2(l+b)

Therefore, the perimeter of the parallelogram will be increased by 2 times.

therefore answer is 2 times
