Question 1145299
A given rectangle has an area of 20 feet what is the length for the various widths
------
<pre>
Area is measured in {{{ units^2 }}}  (e.g. {{{ft^2}}}).

With the information given, all one can say is

LW = 20 {{{ft^2}}}    

where
L = length
W = width   (both measured in feet)

One could also rearrange the above to L=20/W  or  W=20/L,  all three equations are equivalent.
