Answer: 4 √821 m or 114.61 m
Step-by-step explanation:
The diagonal of the football field is like the hypotenuse of a right-angled triangle.
Therefore we can use the Pythagorean Theorem ( hypotenuse = √(side a² + side b²)
∴ the length from one corner to the next diagonally opposite
= √(56² + 100²)
= √(13136)
= 4 √821
