Well, honey, if you paid attention in geometry class, you'd know that the diagonal of a square can be found using the Pythagorean theorem. So, for a 21 ft square, you take 21 squared plus 21 squared, then take the square root of that sum. In this case, the diagonal would be approximately 29.7 feet. Hope that helps, sugar!
18 ft Diagonal of a square is the square root of 2, times the side.
It is 295.16 ft.

About 8.5 feet.
12.73 feet
The diagonal measurement of an 8 ft square is: 11.31 feet.
The diagonal is ~16.97 feet.
Diagonal = square root of (24 squared + 26 squared) and that is square root of (576 + 676) and that is square root of (1252) and that is 35.38 feet
The length of the diagonal is 208.7*sqrt(2) = 295.1 ft.
Since a square has right angles, you can use the Pythagorean Theorem to calculate the diagonal. Specifically, the diagonal of a square is equal to the length of a side, multiplied by the square root of 2.
The diagonal of a 46' x 46' square is 65.05 feet.
The diagonal length of a square with a 900 square foot area is: 42.43 feet.

About 8.5 feet.
No one answer, since it depends on the shape of the 400 square foot figure. If it is a square 20x20, then the diagonal is about 28.25 ft.
