You can put this solution on YOUR website!
let width be: x-5
\n" ); document.write( "Let length be: x\r
\n" ); document.write( "\n" ); document.write( "x(x-5)=84
\n" ); document.write( "x^2-5x=84
\n" ); document.write( "x^2-5x-84=0\r
\n" ); document.write( "\n" ); document.write( "x=5+√25+336
\n" ); document.write( "x=5+19 or x=5-19
\n" ); document.write( "x=24/2 or x=-14/2
\n" ); document.write( "x=12 or x= -7(NO can't be negative)\r
\n" ); document.write( "\n" ); document.write( "L=12
