Mr Mario, at 11:09 you do the proportions incorrectly to my knowledge. If the scale factor is 8/3 and the perimeter is 12, then when you multiply you should be ending up with 32, not a fraction. Am I correct?
This is what I thought also. Since the area of Triangle A is greater than Triangle B, we can safely say that the _perimeter_ of Triangle A will be greater than that of Triangle B, without really knowing Triangle B's perimeter. In the fraction 8/3, the greater number is on the top, and the smaller number is at the bottom. Mario set up a proportion as follows: 8/3 = 12/x, x being Triangle B's perimeter. Since we know that Triangle A's perimeter is greater than that of Triangle B, he put Triangle A's perimeter as the numerator, just like the other fraction. If we ended up with 32, it wouldn't make sense because Triangle B's area is smaller than that of Triangle A, so how can it have a larger perimeter? I hope this helps

I heard that they're making a movie on you. It's like the Super Mario Move or something.
Your on the wrong channel
Nice Tut sir.
Awesome job, thanks ! This helped me complete my assignment. :))
Great to hear!
You look like Johny sins
