Question 104012
A recreational department plans to build a rectangular playground enclosed by 800 meters of fence.  If the length of the playground is 6 meters less than three times the width, find the length and the width of the playground.
------------------
Perimeter = 2*length + 2*width
---------------
Let the width be "x" ft ; length = 3x-6 ft
--------------
EQUATION:
800 = 2*(3x-6) + 2(x)
400 = 3x-6+x
4x= 406 
x = 101.5 feet (width of the playground)
3x-6 = 298.5 feet (length of the playground)
