The perimeter of a fence enclosing a square patio is 60 ft. What is the area of the patio in square feet?

Since a square has four equal sides, each side is \( \frac{\mathrm{60} }{\mathrm{4}} \) or 15 ft.
To solve for the square patio's area:
Area = length of side \u00D7 length of side
\(Area=15ft \times 15ft = 225ft^2\)
