Question #99294

1 Answer

Jul 15, 2017

$L = 800 - 2 W$ $L = 800 -2W$

Explanation:

The fenced area will have three sides, as one side is bordered by the river.

So, The perimeter, $P$ $P$ , of the fence is given by:

$P = L + 2 W$ $P = L+2W$

However, we have 800 yards of fence. Thus:

$P = 800$ $P=800$

Hence:

$L + 2 W = 800$ $L+2W = 800$
$L = 800 - 2 W$ $L = 800 -2W$
