- $a=\sqrt{b}$
- $a ^ 2=b$
- $a=3$
- $a^2=3^2=\boxed{b=9}$

a is diagonal. so it can be calculated like this: a+b+c=5 but its still a thats a positive number. But if we had x then we could add it to a to get x=a. But we have been using this method. So we could do this: a±b±c=-45 a few numbers include this. like 9 12 & 7.

If $a=3$ and $a=\sqrt{b}$ then

$3=\sqrt{b}$

$3^{2}=\left (\sqrt{b} \right )^{2}$

$\boxed{9}=b$

I used a haiku to explain how I got the answer.

Find square root for 3.

Square rooted 9 for answer.

The answer is 9.

Unfortunately, that doesn't follow the 5-7-5 rule .

$a = \sqrt{b}$

$\Rightarrow 3 = \sqrt{b}$

$\Rightarrow 3^2 = (\sqrt{b})^2$

$\Rightarrow b = \color{#D61F06}\boxed{9}$

by substituting $a = 3$ , we will get $\sqrt{b} = 3$ . Square both side, we get $b = 9$

I just learn LaTeX :-D
