Linear measure scales directly.  Just multiply by the scaling factor.

No worries.  We're all in this together.  Just learning.

anonymous · Answer

so I multiply every number by the scale factor?, because someone tried to explain this to me and that what they said to do but I got it wrong. @tkhunny

anonymous · Answer

I figured it out i just have to multiply AB by 0.5

tkhunny · Answer

You must read carefully.  If your scale factor is for linear measure and all the parts are linear measure (length, but not area or volume), then simple multiplication should do the trick.
