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 Cunion has a garden in the shane of a narallelogram. The area of the garden is 738​

Sagot :

Answer:

2 times

Step-by-step explanation:

the length and breadth of the parallelogram will be l and b, respectively.

Then, perimeter = 2(1 + b) [∵ perimeter of parallelogram = 2 x (length + breadth)]

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.

the perimeter of parallelogram will be increased 2 times.
