Perimeter Question #1

In math today, our question we had to answer, on here was : Which method do you prefer? Explain why. There were a couple of different ways people answered them. I think the easiest way for me was, P= ( 2 times length) + ( 2 times width) 46 = ( 2 times 16) + ( 2 times width). I think this was the easiest way for me because I have always done it this way in math. I also do it because it is faster than adding up every side. In this strategy , you just have to go 16 times 2, and 7 times 2. Instead of going 16 + 7 + 16 + 7 = 46.
