Answer:
87 yards
Explanation:
We can represent the situation using the following figure
Therefore, the distance between opposite corners is the hypotenuse of a triangle with legs 63 yards and 60 yards.
Using the Pythagorean theorem, we get that the value of x is:
[tex]\begin{gathered} x=\sqrt[]{63^2+60^2} \\ x=\sqrt[]{3969+3600} \\ x=\sqrt[]{7569} \\ x=87 \end{gathered}[/tex]
Therefore, the answer is 87 yards
