Answer:

21 feet of railing is needed

Explanation:

The diagram which was not included by I know it because I have it for homework this weekend shows the area of the deck:


x^(2)  +  8^(2)

Since we know the area of the deck is 223 square feet:


x^(2)  +  8^(2) = 223

Find 8^{2}[/tex] :

8^{2}[/tex] = 64


x^(2) &nbsp;+ &nbsp;64 &nbsp;= &nbsp;223</p><p></p><p>223 - 64 </p><p>=> 169</p><p></p><p><u><strong>So,</strong></u></p><p></p><p>[tex]x^(2) &nbsp;= 169</p><p></p><p><u><strong>Find square root of 169:</strong></u></p><p></p><p>[tex]√(169) &nbsp;= &nbsp;<strong>13

[tex]x^{2} = 13

Find the longest edge:

x + 8 = 13 + 8

=> 21
