Several uses come to mind. For one, the perimeter of a building, multiplied by the wall height gives an estimate of how much paint, siding, sheathing plywood, etc. are needed to do some work.
For things with a circular shape, say a small lake, you can tell the distance across the lake by walking the perimeter and dividing that distance by pi to get the diameter, i.e., distance . Doing the same kind of thing on a flag pole allows you to decide how long the screws must be to mount a flag pulley.
Another is using the perimeter of something like a lawn or garden to estimate how much seed, fertilizer, or other material is needed when you know that it should be used as so much per acre/square yard/square foot or other area.

When are perimeter used?
Perimeter is used in several real world situations.For example, if your living room is thirteen feet long and twenty feet wide, you know you can't get a rug whose sides are bigger than 13x20.Another common example is fencing. When you are putting up a fence you don't really care about the area. You are looking for how much fencing you will need, which means you need to know how big the perimeter of the land is.In math, perimeter is used in geometry and trigonometry (among other places), and is sometimes used to help student's practice their algebra skills is middle schools.
