Answer:
3.32
Step-by-step explanation:
[tex]4.7 ^2 = 22.09[/tex]
[tex]22.09/2 = 11.045[/tex]
then we can find the square root, [tex]\sqrt{11.045} = 3.32[/tex]
now we can check our answer:
[tex]a^2 + b^2 = c^2[/tex]
[tex]3.32^2 + 3.32^2 = 4.7^2[/tex]
[tex]11.0224 + 11.0224 = 22.0448[/tex]
and [tex]\sqrt{22.0448} = 4.6951[/tex] or 4.7
