You can put this solution on YOUR website!
A = L X W
\n" ); document.write( "Choose EITHER L or X, not both. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Assign Variables:
\n" ); document.write( "(I will choose mine a little bit differently)
\n" ); document.write( "d = length of garden
\n" ); document.write( "d = 20 feet
\n" ); document.write( "w = width of garden
\n" ); document.write( "A = area of garden\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Equations and Solution:\r
\n" ); document.write( "\n" ); document.write( "\"A=d%2Aw\" and perimeter given as 64 feet means \"2d%2B2w=64\".
\n" ); document.write( "We know what is the d value, so we want to solve for w.
\n" ); document.write( "-
