A rectangular rug has the length of 12 feet and a diagonal of 20 feet. What is the perimeter of the rug?
\n" ); document.write( "diagonal^2 = l^2+b^2
\n" ); document.write( "20^2=12^2+b^2
\n" ); document.write( "b^2=400-144=256
\n" ); document.write( "b=16'
\n" ); document.write( "perimeter = 2(l+b)=2(12+16)=56'
\n" ); document.write( "
\n" );
