How much will it cost to fence in a field that is 12 feet long and 42 feet wide with fence that cost $10 a yard? Correct Answer $360

1 yard = 3 feet Thus, Length of the field = 12 feet = 4 yard Width of the field = 42 feet = 42/3 yard = 14 yard Now, Total length of the fence = (2*4) + (2*14) yards = 36 yards As, the cost of one yard is 10, therefore cost of 36 yard = 36*10 = 360.
