A farmer needs to build a goat pen. The pen will be 7 yards wide and 16 yards long. The fencing material costs $3.00 per yard. How much will it cost to buy enough fencing material to build the goat pen?
The perimeter of the goat pen is:
2(7) + 2(16) = 14 + 32 = 46 yards
Therefore, the farmer needs to buy 46 yards of fencing material.
The cost of the fencing material is:
46 yards x $3.00 per yard = $138.00
So it will cost the farmer $138.00 to buy enough fencing material to build the goat pen.
