Use Pythagoras' theorem:
62+42 = 52 and the square root of this is 7.211102551
Answer: 7.211102551 units
The diagonal is about 28.3 feet.
The dimensions of a square containing 2.5 acres are:330 feet per side1,320 foot perimeter466.7 foot diagonal lengthAn area of 108,900 square feet
The diagonal of a 5 foot square is about 7.07 feet.
The diagonal is ~5.656 feet.
There is an infinite number of possible answers to this question, but I will give two possible answers. 1. 1 foot by 217,800 feet 2. 100 feet by 2178 feet

The diagonal dimension is 11.31 feet.
Your question cannot be answered. An area of 14 acres is equivalent to 609,840 square feet, but a rectangle with that area could be 609,840 feet by 1 foot, or it could be 1089 feet by 560 feet, or many other possible dimensions, each of which would have a different perimeter.
The diagonal of a 36 x 36 foot square is 50.91 feet.
The diagonal is ~16.97 feet.
Diagonal = 18*sqrt(2) = 18*1.414214 = 25.45584 feet
