Question

if the sides of a parallelogram are increased to twice its original lengths ,how much will the perimeter of the new parallelogram? ​

Answer 1

Answer:

If both sides are increased twice, then new length and breadth will be 21 and 2b, respectively. Now, new perimeter = 2(21 + 2b) = 2 x 2(l + b) = 2 times of original perimeter. Hence, the perimeter of parallelogram will be increased 2 times.
