**drwls**, Wednesday, February 6, 2013 at 11:03amThe diagonal of a square is sqrt2 times the length of a side. You can prove that with the Pythagorean theorem.

Sqrt2 = 1.4142

250 x sqrt2 = 353.6

**Ms. Sue**, Wednesday, February 6, 2013 at 11:32amSuppose each side of the square is 100 feet long.

Use the Pythagorean Theorem.

a^2 + b^2 = c^2

100^2 + 100^2 = c^2

1,000 + 1,000 = c^2

2,000 = c^2

44.72 = c
