2l+2w = 90 (1)
\n" ); document.write( "and
\n" ); document.write( "l = 4w-5 Use this value for l in equation (1):
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "2(4w-5)+2w = 90
\n" ); document.write( "8w-10+2w = 90
\n" ); document.write( "10w = 100
\n" ); document.write( "w = 10 so this is the width. And the length:
\n" ); document.write( "l = 4w-5 = 4(10)-5 = 40-5 = 35 The length is 35
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "Check:
\n" ); document.write( "2(35)+2(10) = 70+20 = 90 Correct.
\n" ); document.write( "
