Which color line is longest? Blue, red, or yellow.

First, let’s find the length of the blue line. We can calculate its length by adding the length of each side. So the length of the blue line is two squares. One plus one equals two. Next, we need to calculate the length of the red line. This line is five squares in length. Four plus one equals five.

And finally, we need to calculate the length of the yellow line. The yellow line is four squares long. Three plus one equals four. So the red line is the longest.
