Answer:
\textsf{Option A, 13}

-------------------------------------------------------------------------------------------------------------

Given:
\textsf{Side length = 9 units}

Find:
\textsf{Diagonal length}

Solution: The diagonal length can be easily determined using an equation which uses the side length of a square multiplied by the square root of 2. All we need to do is plug in the values and simplify the expression.

Plug in the values


  • \textsf{Diagonal = Side length} * √(2)

  • \textsf{Diagonal = 9 units} * √(2)

Simplify the expression


  • \textsf{Diagonal = 9 units * 1.4142}

  • \textsf{Diagonal = 12.73 units}

Looking at the answer options that have been provided, the option that best fits our scenario is option A, 13.
