Anyone know the answer to this?!?!

Answer:
C: 3 x 4 x 4
Step-by-step explanation:
It's obvious for an European since it's simple approximation, the cm is just thrown in to confuse Americans.
For this case we have the MNP triangle whose sides measure:
[tex]L1: 3.5cm\\L2: 4.1cm\\L3: 4.3cm[/tex]
If we want to find a similar triangle, it must have a scale factor "x" on each side with respect to the MNP triangle. So:
[tex]L1 ':( x) 3.5cm\\L2 ':( x) 4.1cm\\L3 ':( x) 4.3cm[/tex]
If [tex]x = 10[/tex] we get:
[tex]L1 ': 35cm\\L2 ': 41cm\\L3 ': 43cm[/tex]
