STARTINF NOYES:
Since the perimeter is measured in meters, we will measure length and width in meters, and we will calculate area in square meters.
There is usually more than one way to solve a problem. I'll show you some ways. Use the way to solve the problem that you think your teacher prefers, or the one the teacher thinks is the right way to do it. (Your teacher may not like to use the --> arrows that I use, for example).

DEFINING VARIABLES AT THE START:
= width
Length =
Perimeter =
Area = Length X Width or
Area =
{You could use or anything else instead of ).

ONE WAY FROM THERE ON:
--> --> -->
The width is 3 meters.
From here:
Length = 3 x 3 meters = 9 meters and
Area = Length X Width = (9 meters) X (3 meters) = square meters

FANCIER:
After finding ,
--> --> --> (in square meters) or

TOO FANCY:
-->
--> <-->
So or
The easier calculation is
--> --> --> (in square meters) or
