a farmer needs to build a goat pen. the pen will be 9 yards wide and 18 yards long. The fencing material costs 8.98 per yard. how much will it cost to buy enough fencing material

Answers

Answer:

$484.92

Step-by-step explanation:

Since you have 4 sides to the pen you will need to figure out how many yard total there is so two of your sides are 9 yards and the other two are 18 yards. now you have to add however many yards there are....

9+9=18

18+18=36

then you have to add those two numbers together

18+36=54 yards total

now you just multiply 54 by 8.98

your total amount of money you spent is $484.92
