document.write( "Question 144660: A rectangle has a diagonal that is 3.6 feet longer than the length and 7.1 feet longer than the width. What are the dimensions of the rectangle? I would appreaciate it if someone could help me solve this problem. This is what I've done so far but I know its not correct. Thank you for your time.

You can put this solution on YOUR website!
let x=diagonal, so x-3.6=length and x-7.1=width\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x^2=(x-3.6)^2+(x-7.1)^2 __ x^2=x^2-7.2x+12.96+x^2-14.2x+50.41\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "subtracting x^2 __ 0=x^2-21.4x+63.37\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "use quadratic formula to find x
\n" ); document.write( "
