K equivalent in springs arranged in parallel combination

I do know the formula for k equivalent in springs is

k1 + k2

But for this following question I don't think just writing the equation would be enough for 2 marks.

Q) If two springs, each of stiffness k, are connected side-by-side in parallel, the stiffness of the combination is 2k. Explain why.

So how do I explain?

Thank you all for your fantastic help and support!:smile:
F=ke, when you apply force F on 2 spring, extension is only e/2 so stiffness is 2k.

Thanks a lot Arctic Kitten! (:
