A rectangular field with a length of 28 feet and an area of 672 square feet is to be enclosed by a fence. How much will it cost to purchase the fence if it sells for $3.50 per linear foot?

Answer :

Final answer:

The given rectangular field has a length of 28 feet and an area of 672 square feet. The perimeter is calculated as 104 feet, and given that the fence costs $3.50 per linear foot, the total cost for the fence would be $364.

Explanation:

The subject of this question is mathematics, as it involves calculations using area, length and cost per foot to determine the total cost of the fence. The length of the rectangular field is given as 28 feet, and the area as 672 square feet. The width can be calculated by dividing the area by the length (672 ft² ÷ 28 ft = 24 ft).

The perimeter of the rectangle (the total length of the fence needed) is calculated by the formula 2*(length+width), which in this case is 2*(28 ft + 24 ft) = 104 feet. If the fence costs $3.50 per linear foot, the total cost will be 104 ft * $3.50/ft = $364.
