Example
Here is a drawing of a grass
lawn. The real length of
each side of the lawn is
4 m
5 m
Did you know?

8 m
20 m
6 m
given. What is the perimeter
of the lawn?
10 m
3 m
Add the lengths of all the
sides:
means 'measure', So
the word 'perimeter
means 'measure-
around'.
20 m
10 m + 20 m + 20 m + 4 m + 8 m + 3 m + 6 m + 5 m
= 50 m + 12 m + 14 m
= 76 m
