The length of a particular rectangle is 
greater than the width of the rectangle. If the perimeter of the rectangle is 
, what is the area of the rectangle?
The length of a particular rectangle is
If the width is 
, then the length is 
. The perimeter equals 
, so 
.
solving for 
, we have 
, the width, so the length is 
.
Then, to find the area we multiply 
times 
, which equals
