In rectangle with width=w, length=l and diagonal=d we have:
\n" ); document.write( "\"w%5E2%2Bl%5E2=d%5E2\"
\n" ); document.write( ":
\n" ); document.write( "For the given values we have:
\n" ); document.write( "\"5%5E2%2Bl%5E2=8%5E2\"
\n" ); document.write( "\"25%2Bl%5E2=64\"
\n" ); document.write( "\"l%5E2=39\"
\n" ); document.write( "\"l=sqrt%2839%29\"
\n" ); document.write( "l=6.24499 -> rounded to the nundreth -> l=6.24 ft
\n" ); document.write( ":
\n" ); document.write( "Area of the rectangle is
\n" ); document.write( "\"A=w%2Al\"
\n" ); document.write( "\"A=5%2A6.24\"
\n" ); document.write( "\"A=31.20\" -> area is 31.20 sqf
\n" ); document.write( "
\n" );
