length = 35 cm
\n" ); document.write( "perimeter = 110 cm
\n" ); document.write( " formula : perimeter = 2*(length+width)
\n" ); document.write( " 110 = 2(35+width)
\n" ); document.write( " 110 = 2*35+2*width
\n" ); document.write( " 110 =70+2*width
\n" ); document.write( " move 70 to the left
\n" ); document.write( " 110 -70 = 2*width
\n" ); document.write( " 40 = 2*width
\n" ); document.write( " divide with 2 on both sides
\n" ); document.write( " \"+40%2F2+=+2%2Awidth+%2F2\"
\n" ); document.write( " 20 = width
\n" ); document.write( "width = 20 cm\r
\n" ); document.write( "\n" ); document.write( "
