Question

If you have a rectangle with a width of 5 and length of 13 and make a diagonal line in it, would the length of that line be 18?

Answer 1

Pythagorean
\(\Rightarrow 5^2 + 13^2 = c^2 \)

Answer 2

use pythagorean to verify

\[18 = \sqrt{5^2 + 13^2}?\]
\[18 = \sqrt{25 + 169}?\]
\[18 = \sqrt{194}\]
\[\sqrt{194} = 13.93\]
