Study Notes

Perimeter is the distance around the outside of a shape
Perimeter is found by adding together the length of all a shape's sides
Examples of perimeter include the lines around the edge of a soccer field and the curb around a parking lot

In a rectangle, opposite sides are equal
To find the perimeter of a rectangle, add the length of all four sides together
Example: door with sides of 8 inches and 4 inches has a perimeter of 24 inches (8 + 8 + 4 + 4)

A hexagon is a shape with six sides
To find the perimeter of a hexagon, add the length of all six sides together
Example: window with six sides of 3 inches each has a perimeter of 18 inches (3 + 3 + 3 + 3 + 3 + 3)

An irregular polygon is a shape with sides that are not equal to each other
To find the perimeter of an irregular polygon, add the length of all the sides together
Example: fence with twelve sides of varying lengths has a perimeter of 133 inches (18 + 20 + 4 + 15 + 15 + 6 + 5 + 4 + 8 + 14 + 4 + 20)
