$\"P=2L%2B2W\"$ use perimeter formula
\n" ); document.write( " $\"P=1280\"$
\n" ); document.write( " $\"W=L-90\"$
\n" ); document.write( "substitute and solve for $\"L\"$
\n" ); document.write( " $\"P=2L%2B2W\"$ substitute P and W
\n" ); document.write( " $\"1280=2L%2B2%28L-90%29\"$ distribute the 2
\n" ); document.write( " $\"1280=2L%2B2L-180\"$ add like terms
\n" ); document.write( " $\"1280=4L-180\"$ add 180
\n" ); document.write( " $\"1460=4L\"$ divide by 4
\n" ); document.write( " $\"highlight%28365=L%29\"$
\n" ); document.write( " $\"W=L-90\"$ substitute L
\n" ); document.write( " $\"W=365-90\"$ subtract
\n" ); document.write( " $\"highlight%28W=275%29\"$ \n" ); document.write( "

\n" );
