00:00:02.930 --> 00:00:05.200
Which color line is longest?
00:00:05.770 --> 00:00:08.090
Blue, red, or yellow.
00:00:10.830 --> 00:00:13.980
First, letâ€™s find the length of the blue line.
00:00:16.480 --> 00:00:20.520
We can calculate its length by adding the length of each side.
00:00:22.890 --> 00:00:26.390
So the length of the blue line is two squares.
00:00:28.640 --> 00:00:30.730
One plus one equals two.
00:00:33.720 --> 00:00:37.010
Next, we need to calculate the length of the red line.
00:00:39.700 --> 00:00:42.120
This line is five squares in length.
00:00:42.260 --> 00:00:44.410
Four plus one equals five.
00:00:46.220 --> 00:00:50.160
And finally, we need to calculate the length of the yellow line.
00:00:54.020 --> 00:00:56.280
The yellow line is four squares long.
00:00:56.800 --> 00:00:58.850
Three plus one equals four.
00:01:01.150 --> 00:01:03.440
So the red line is the longest.
