P = 2L +2W \n" ); document.write( "44 = 2L + 2W \n" ); document.write( "L = 3W \n" ); document.write( "Substitute \n" ); document.write( "44 = 2(3W) + 2W \n" ); document.write( "44 = 6W + 2W \n" ); document.write( "44 = 8W \n" ); document.write( "Divide each side by 8 \n" ); document.write( "44/8 = W \n" ); document.write( "Reduce \n" ); document.write( "5 1/2 = W \n" ); document.write( ". \n" ); document.write( "If you know the width is 5.5, and the length is 3*5.5, then the length is 16.5. \n" ); document.write( "Prove it by putting in the values: \n" ); document.write( "2(16.5) + 2(5.5) = 44 \n" ); document.write( "33 + 11 does indeed equal 44 \n" ); document.write( " |
