Answer 1

Observe that the length of the ladder refers to the hypotenuse of the right triangle formed. So, we have to use Pythagorean's Theorem

`c^2=a^2+b^2`

Where c = h, a = 9, and b = 7.

`\begin{gathered} c^2=9^2+7^2 \\ c^2=81+49 \\ c=\sqrt[]{130} \\ c\approx11.40 \end{gathered}`

Hence, the ladder is 11.40 meters long.
