00:00:00.000 --> 00:00:05.155
Here is the problem: What is the perimeter of a rectangle with length 8 and width 5?

2
00:00:05.605 --> 00:00:08.148
Rectangle with length 8 and width 5.

3
00:00:08.948 --> 00:00:12.988
Read the problem. L equals 8, W equals 5.

4
00:00:13.438 --> 00:00:19.057
Area. A equals L times W equals 8 times 5 equals 40.

5
00:00:19.507 --> 00:00:26.845
Perimeter. P equals 2L plus 2W equals 16 plus 10 equals 26.

6
00:00:27.645 --> 00:00:33.380
So the answer is Area equals 40 square units; perimeter equals 26 units.

7
00:00:33.830 --> 00:00:39.252
Area counts square units inside the shape; perimeter is the distance around it.

8
00:00:40.052 --> 00:00:43.744
40 over 5 equals 8, which checks out.
