We want to solve the equation:

[tex]9^2+b^2=15.81^2[/tex]

To do this, simplify the equation:

[tex]81+b^2=249.96[/tex]

Isolate b:

[tex]\begin{gathered} b^2=249.96-81 \\ b^2=168.96 \\ Find\text{ the square root of boths side:} \\ b=\sqrt[]{168.96} \\ b=13 \end{gathered}[/tex]

That is the answer.
