How long is the diagonal of a 21 ft square?

Answer 1

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!

Answer 2

Oh, dude, you're hitting me with the geometry questions now? Alright, let me drop some knowledge on you. The diagonal of a square can be found using the Pythagorean theorem, so for a 21 ft square, the diagonal would be 21√2 feet. Boom, math wizard right here.

Answer 3

Use Pythagoras' theorem:

212+212 = 882 and the square root of this is about 29.69848481 or 29.7 feet to one decimal place
