Answer:
Step-by-step explanation:
A square enclosure would have all sides of equal length. Thus, a perimeter of 16 feet would have 4 sides (16/4) or 4 feet in length. The diagonal would form a right triangle with two sides of 4 feet each.
The diagonal, the hypotenuse, is determined by:
4^2 + 4^2 = x^2
32 = x^2
x = 5.6569 feet
