In 1L we’re working on making rectangles with a perimeter of 24. That means that if we count up the edges, we get 24 as an answer.

There are a few different ways to make a rectangle with a perimeter of 24. Here’s a rectangle that is 1 by 11. If we add up 1+11+1+11 it makes 24.

we saw some patterns when we organized all of our rectangles by size. When the length increases the width decreases. We also noticed that length plus width is always 12 in this case. Which is half of the perimeter.

So another way to calculate perimeter is to add length and width and then double the answer.
