How do i get the magnitudes to match? (2 Viewers)

Ive gotten a perpendicular vector to the one in the question 2i + 5j, how do i morph this into the required magnitude of 12?
(Do i have to convert it to unit vector maybe?)

Find the unit vector of that vector and then multiply it by 12.

Convert it to unit vector then simply multiply by 12.
