Since it is a square, both the length and the width are equal. Both are 10 inches.
We will use Pythagoras Theorem to find the diagonal of the square.
[tex]\boxed { \boxed {a^2 + b^2 = c^ }}[/tex]
[tex]c^2 = 10^2 + 10^2[/tex]
[tex]c^2 = 100 + 100[/tex]
[tex]c^2 = 200[/tex]
[tex]c = \sqrt{200} [/tex]
[tex]c = 14.1 \text { inches}[/tex]
[tex]\boxed {\boxed {\text {Answer: The hypotenuse is 14.1 inches}}}[/tex]
