1. 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?
- A. $180
- B. $180
- C. $180
- D. $180
Answer: Option B
Explanation:
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.
