Answer:

12.73m

Step-by-step explanation:

using Pythagoras theorem

a = x (i change x to a for easy reference due to multiplication)

18 x 18 = a x a + a x a

324 = 2a^2

a^2 = 324 / 2= 162

a = $\sqrt{162}$ = 12.7279 = 12.73 (2 decimal place)

The answer is incomplete because of the law of the quadratic formula which doesn’t allow this question to be totally solved because of the singularity that intercepted the form of quantum mechanics

So hmm check the picture below

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
variation
\end{array}\\\\
-------------------------------\\\\
\textit{we know that }
\begin{cases}
x=3\\
y=1
\end{cases}\implies 1=k3\implies \cfrac{1}{3}=k
\\\\\\
thus\qquad \qquad y=\cfrac{1}{3}x$
