Understanding perimeter and circumference can be fun when you see how they apply to everyday life! Here are some easy examples:
Fencing a Garden: If you want to know how much fence you need for your garden, you need to find the perimeter. For a rectangular garden, if one side is and the other side is , you can find the perimeter with this formula:
P = 2(a + b).
Pizza Size: When you’re picking out a pizza, it’s helpful to talk about the circumference! For a pizza with a radius (the distance from the center to the edge) of , you can find the circumference using this formula:
C = 2πr.
Running Track: If your school has a circular track, you can also find its circumference. Just use the same formula:
C = 2πr.
These everyday examples make learning about measurements really interesting!
