Calculate the perimeter of a square in meters whose side length is 38 meters.

First, let’s sketch our square. We know that this square has a side length of 38 meters. We also know that in a square, all four sides are the same length. And we can label them as such. The perimeter of a square is the distance all the way around the square. We can find the perimeter by adding up all four sides. Or, we can find the perimeter by multiplying one of the side lengths by four.

Because in a square, each side measures the same length, instead of adding four times, we’ll just multiply. The perimeter of this square can be found by multiplying four times 38. We set up our multiplication problem. Starting in the units, we multiply eight times four which is 32. Write down our two. And carry our three. From there, we multiply the tens place, four times three equals 12. And we need to add the three we carried over. 12 plus three is 15. Write down the five and carry the one. From there, we just bring down the one. Four times 38 equals 152.

The perimeter, the distance around this square, is 152 meters.
