So that you can find out how long it will tkae you go around it
We need to know the shape of the object.
Laying turf then fencing it in
That's oddly worded. You can't find the area of a perimeter. Either way, we need to know how many sides there are. A square with 6-inch sideshas a perimeter of 24 inches and an area of 36 square inches.
The answer depends on what information you have about the regular polygon. You need to know, or be able to derive, the number of sides (n) and the length of each side (L). Then the perimeter is n*L units of length.
Perimeter is the distance around something. In the case of a circle (or other curved figures), this is simply called the perimeter, so I would say perimeter is the same as circumference. Except that it is uncommon to call the circumference of a circle the "perimeter".
If you know the perimeter, there is no need to find it again.
You need to know perimeter when you're fencing the yard. You need to know area when you're mowing it, seeding it, fertilizing it, buying it, or selling it.
That is the area. The perimeter is the measure around something, and it is relevant, among other things, to know how much fencing you need for a lot.
You need to find perimeter when you buy a house, because then you know where your yard begins and ends.
You need the length...
i know it has something to do with having a constant width , i know it has something to do with having 3 arcs and i know that it is the width x pi but why is this? i need a very simple sollution in relation to the circumference of a circle
You need to know what the shape is before you can even think about trying to calculate its perimeter.
Length + width = half of perimeter, so you need more information...
no No. You need to know the length of a rectangle's sides in order to calculate the perimeter.
When you want to build a fence around your house, you need to know the perimeter.
yes ,becaus you need to know how much fence you need
