Question 1166158: A livestock pen is built in the shape of a rectangle that is
2 times as long as it is wide. The perimeter is 54 feet. If the material used to build the pen is $1.25 per foot for the longer sides and
$2.25 per foot for the shorter sides (the shorter sides have gates, which increase the cost per foot), find the cost to build the pen.

short side is x
long side is 2x
the perimeter is 2 of each or a total of 6x
6x=54 and x=9 ft short side @$2.25 per foot is $20.25
18 ft longer side @$1.25=$22.50
Total is $42.75
