The wood costs $5 per yard so putting a wooded fence along the side of length x yards will cost 5x dollars. The steel fencing costs $100 per yard so fencing the remaining two sides with steel fencing will cost 10(150  x) dollars. The total cost for the fencing is $1200. Can you complete the problem now? If you need further assistance write back. Penny
