Question 1154032
How did you get 241.3 feet?
The two sides of the field form 2 sides of a right triangle and the distance from one corner to the other is the hypotenuse. I think you have figured that out already.
If you apply the Pythagoras theorem, the hypotenuse =
{{{sqrt(223^2+ 63^2) = sqrt(53698) = 231.7}}} feet

(rounded off to the nearest 10th of a foot.

Please check the input values and your calculations again. Hope this helps.
