Answer: [tex]\bold{4\sqrt2}[/tex]
Step-by-step explanation:
[tex]A_{triangle}=\bigg(\dfrac{1}{2}\bigg)b\times h[/tex]
[tex]A_{triangle}=\bigg(\dfrac{1}{2}\bigg)4\times 16[/tex]
[tex]=\bigg(\dfrac{1}{2}\bigg)64[/tex]
[tex]=32[/tex]
[tex]A_{square}= s^2[/tex]
[tex]32 = s^2[/tex]
[tex]\sqrt{32}=s[/tex]
[tex]\sqrt{\underline{2\cdot 2}\cdot \underline{2\cdot 2}\cdot 2}=s[/tex]
[tex]2\cdot 2\sqrt{2}=s[/tex]
[tex]4\sqrt{2}=s[/tex]
