Question

If the side of a parallelogram are increased to twice their original lengths, by how many times will the perimeter of the new parallelogram increase?​

Answer 1

We know that, perimeter of parallelogram = 2 (length + breadth)

If the sides of a parallelogram are increased to twice its original lengths.

= 2 (2length + 2breadth)

= 2 × 2 (length + breadth)

Hence, the perimeter will increase by 2 times the perimeter of the original parallelogram.
