You have P = 472 feet of fencing to enclose a rectangular plot that borders on a river. If you do not fence the side along the r
Ray Of Light [21]
The width would be 236 and the lengths would be 118

Use the equations 2L+W=472 and W*L=MAX
Change the first equation to W=472-2L and plug this into the other equation
(472-2L)(L)=MAX
472L-2L^2=M (take derivative)
472-4L=0 (set to 0 to find the max value)
4L=472 
L=118 
Plug into original to get W=236

Hope this helps!

tia_tia [17]
<h2><u>Answer</u></h2>

11 209/250

<h2><u>Explanation</u></h2>

5.815 + 6.021

First add the numbers the way they are.

          5.815

       <u> +6.021</u>

      <u>   11.836</u>

The whole number is 11.

11.836 = 11 + 0.836

0.836 = 836/1000

Dividing byy 4 we get,

0.836 = 836/1000 = 209/250

∴ 11.836  = 11 209/250
