Final answer:
To calculate the amount of wire needed to enclose a square plot of land, multiply the length of one side by 4.
Step-by-step explanation:
To calculate the amount of wire needed to enclose a square plot of land, we need to find the perimeter of the square. The perimeter of a square is equal to four times the length of one side. Therefore, to find the amount of wire needed, we can multiply the length of one side by 4:
Perimeter = 4 x Side Length
Given that the length of one side is 15 feet, the perimeter of the square plot of land would be:
Perimeter = 4 x 15 = 60 feet.
