A property measures 75 feet by 120 feet. If the cost of fencing is $15 per linear foot, how much would it cost to fence the entire perimeter of the property?
- A$5,400
- B$3,450
- C$4,300
- D$2,700
Show answer & explanationAnswer & explanation
Correct answer: A. $5,400
First, calculate the perimeter: 2 * (75 feet + 120 feet) = 2 * 195 feet = 390 feet. Then, multiply the perimeter by the cost per linear foot: 390 feet * $15/foot = $5,850.
Why the other options are wrong
- B. This calculation suggests an error in calculating the perimeter or multiplying by the cost.
- C. This option is incorrect and likely results from a calculation error.
- D. This calculation might result from calculating the area instead of perimeter or using incorrect dimensions.
Perimeter Calculation
The total distance around the boundary of a two-dimensional shape, often used for fencing or landscaping costs.
- For a rectangle: 2 × (length + width).
- Measured in linear units (feet, meters).
- Used to calculate costs per linear unit.
