The length of a rectangle is 5 feet less than the width. The perimeter of the rectangle is 90 feet. Find the length.
\n" ); document.write( "
\n" ); document.write( "\"L=W-5ft\"
\n" ); document.write( "\"P=2%28L%2BW%29\", working eqn
\n" ); document.write( "Then,
\n" ); document.write( "\"90ft=2%28W-5%2BW%29\"
\n" ); document.write( "\"90=2%282W-5%29\" ----> \"90=4W-10\" ----> \"90%2B10=4W\"
\n" ); document.write( "\"cross%284%29W%2Fcross%284%29=cross%28100%2925%2Fcross%284%29\"
\n" ); document.write( "\"W=25ft\"
\n" ); document.write( "\"L=25-5=20ft\" ANSWER
\n" ); document.write( "Go back working eqn,
\n" ); document.write( "\"90=2%2825%2B20%29\"
\n" ); document.write( "\"90=2%2845%29\"
\n" ); document.write( "\"90ft=90ft\"
