The length and with are the legs of a triangle,
\n" ); document.write( "and the diagonal is the hypotenuse.
\n" ); document.write( "So \"w%5E2+%2B+%282w%2B44%29%5E2+=+%282w%2B46%29%5E2\"
\n" ); document.write( "subtract \"%282w%2B46%29%5E2\" from each side.
\n" ); document.write( "\"w%5E2+%2B+%282w%2B44%29%5E2+-+%282w%2B46%29%5E2=+0\"
\n" ); document.write( "\"w%5E2+%2B+4w%5E2+%2B+176w+%2B+1936+-+%28+4w%5E2+%2B+184w+%2B+2116+%29+=+0\"
\n" ); document.write( "\"w%5E2+%2B+-8w+-180+=+0\"
\n" ); document.write( "factoring,
\n" ); document.write( "\"%28w%2B10%29%28w-18%29+=+0\"
\n" ); document.write( "So w = -10 or w = 18
\n" ); document.write( "Since we need a positive width, w = 18
\n" ); document.write( "The length is 2w+44 = 2(18) + 44 = 36 + 44 = 80
\n" ); document.write( "The diagonal is 2w + 46 = 2(18) + 46 = 36 + 46 = 82
\n" ); document.write( "Notice that 18^2 + 80^2 = 82^2
\n" ); document.write( "
\n" );
