Question 1019712: A livestock pen is built in the shape of a rectangle that is twice as long as it is wide. The perimeter is 48 feet. If the material used to build the pen is $2.25 per foot for the longer sides and $4.25 per foot for the shorter sides (the shorter sides have gates, which increase the cost per foot), find the cost to build the pen. Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Let = the width = the length
---------------------
Use the formula for perimeter:
-----------
The 2 shorter sides add up to: ft
The 2 longer sides add up to: ft
------------------------
Let = the cost to build the pen
$140
