Question

The older square-shaped floppy diskettes measured 5 inches on each side.

What was the diagonal length of a diskette?

OA) 50 in.

OB) 55 in.

OC) 51 in.

OD 58 in.

Answer 1

A

Explanation:

I took the test

Answer 2

Option A is the correct answer.

Explanation:

Refer the figure given.

We have

AB = 5 inches

DA = 5 inches

By Pythagoras theorem we have

DB² = AB² + AD²

DB² = 5² + 5²

DB² = 50

`DB=√(50)in\\\\\texttt{Length of diagonal = }√(50)in`

Considering square root missing from options given

Option A is the correct answer.
