Use the Pythagoras theorem:-

diagonal^2 = 5^2+5^2 = 50
diagonal = sqrt 50 = 7.1 inches to nearest tenth

It is given that the plate is a square.

Therefore, let us represent the side of the square by the variable, "a".

Therefore, it is given to us that:
a=5 inches.

Now, we have to find the diagonal of the square. We know that the diagonal,
d of a square is given by the formula:


d=a√(2)

Applying the above formula to our case we get the diagonal to be as:


d=5√(2)\approx7.07 inches.

Therefore, the length of the diagonal to the nearest tenth of an inch is:


d=7.1 inches.
