1.	If the sides of a parallelogram are increased to twice its original lengths, how much will the perimeter of the new parallelogram?(a) 1.5 times (b) 2 times (c) 3 times (d) 4 times
Answer» (b) 2 times 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.

If the sides of a parallelogram are increased to twice its original lengths, how much will the perimeter of the new parallelogram?(a) 1.5 times (b) 2 times (c) 3 times (d) 4 times

Answer»

(b) 2 times

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.
