If a square plate has side lengths of 5 inches, what is the length of the diagonal to the nearest tenth of an inch?

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: inches.

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

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