Final answer:
To find the cost to enclose a rectangle, calculate the perimeter using the formula P = 2(length + width) and then multiply by the cost per yard of the fencing material.
Step-by-step explanation:
To calculate the cost to enclose a rectangular field with fencing, you need to know the perimeter of the rectangle. The formula for the perimeter P of a rectangle is P = 2(length + width). In this case, the field has dimensions of 69 yards by 119 yards.
So, the perimeter P is calculated as: P = 2(69 + 119) = 2(188) = 376 yards. Now, if you have the cost per yard for the fencing materials, you can multiply this by the perimeter to find the total cost. For example, if the fencing costs $5 per yard, the total cost would be 376 yards x $5/yard = $1880.
