Answer:
(B)[tex]\sqrt{2} ft[/tex]
Step-by-step explanation:
Given a Square of side 1 foot, the length of the diagonal is determined using the Pythagoras theorem.
The diagonal is the hypotenuse of the right triangle obtained.
From Pythagoras Theorem,
[tex]Hypotenuse^2=Opposite^2+Adjacent^2\\=1^2+1^2\\=1+1\\Hypotenuse^2=2\\Therefore, Hypotenuse=\sqrt{2} ft[/tex]
The length of the diagonal is [tex]\sqrt{2} ft[/tex]
